Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The interface bridge has the function of interface protocol conversion, and can convert the original interface protocol of the interface into another interface protocol, so that the interface with the converted interface protocol is obtained, and the use requirements of the interfaces with different interface protocols are met; the protocol level of the original interface protocol may be higher than the protocol level of another interface protocol after the conversion, or the protocol level of the original interface protocol may be lower than the protocol level of another interface protocol after the conversion; that is, the interface bridge may implement conversion from a higher level original interface protocol to another interface protocol at a lower level, or vice versa. For example, for an interface protocol (PCIE 5.0 interface protocol) having higher usage performance, i.e., a higher level, after interface protocol conversion using the interface bridge, the original lower level interface protocol (PCIE 4.0 interface protocol) is converted into PCIE5.0 interface protocol; the converted interface has the performance of PCIE5.0 interface protocol, and the use effect which cannot be realized by the original interface protocol can be improved.

The operation of the interface bridge will be described using the high-speed serial interface PCIE as an example. In order to meet the requirement of the data transmission rate, the transmission rate of the interface is improved, so that interfaces with different transmission rates appear, and in order to meet the requirement of the data transmission rate on the basis of a high-speed serial interface PCIE4.0, an interface protocol of the PCIE4.0 interface is upgraded, for example, the speed of the high-speed serial interface (PCIE, PERIPHERAL COMPONENT INTERCONNECT EXPRESS)) 4.0 interface is 16GT/s, and in order to meet the requirement of the data transmission rate, the PCIE4.0 interface is upgraded to a PCIE5.0 interface, so that the speed of the PCIE5.0 interface is improved to 32GT/s.

It should be noted that, the high-speed serial interface PCIE is a high-speed bus inside the computer, and belongs to a point-to-point structure. For ease of understanding, please refer to fig. 1, fig. 1 is a schematic diagram of a high-speed serial interface in a computer.

As shown in FIG. 1, a high-speed serial interface may be formed by a root node (root port) and an endpoint (endpoint) directly into a point-to-point connection pair, and when a high-speed serial interface extender (PCI-Express switch, PCIE SWITCH) exists in an architecture inside a computer, the high-speed serial interface extender may be connected to multiple endpoints at the same time.

Meanwhile, the PCIE of the high-speed serial interface is a layered structure, and is mainly divided into a transaction layer, a data link layer and a physical layer. Wherein the Transaction layer is mainly responsible for creating (sending) or parsing (receiving) Transaction Layer Packets (TLPs), flow control, quality of service (Quality of Service, qoS), transaction ordering; the main responsibilities of the data link layer are creating (sending) or parsing (receiving) data link layer packets (DATA LINK LAYER PACKET, DLLP), accept/reject (Ack/Nak) protocols, flow control, power management; the main responsibility of the physical layer is to process the data physical transmission of all the transaction layer data packets, the sending end of the physical layer distributes the transaction layer data packets to each Lane (line) for transmission, the receiving end of the physical layer gathers the transaction layer data packets on each Lane (line), scramble (scrambling for the purpose of uniformly distributing 0 and 1 and removing electromagnetic interference of channels), de-scramble (descrambling), 8/10 or 128/130 codec, and the like. When a designer designs the high-speed serial interface PCIE, the transaction layer, the data link layer, and the physical layer may be further divided into a medium layer (MEDIA ACCESS LAYER, MAC), a physical coding layer (Physical Coding Sublayer, PCS), and a physical connection layer (PHYSICAL MEDIA ATTACHMENT LAYER, PMA). The MAC layer and the PCS layer in the high-speed serial interface PCIE are connected through a PIPE interface (PHY INTERFACE For the PCI Express), and the PIPE interface is an interface corresponding to a PIPE interface protocol.

After the PCIE is upgraded, the PIPE interfaces corresponding to the MAC layer and the PCS layer are also required to be upgraded, for example, after the PCIE4.0 interface is upgraded to the PCIE5.0 interface in the foregoing description, in order to solve the problem of signal crosstalk existing in the PCIE5.0 interface at the speed of 32GT/s, for the PCIE5.0 interface, a PIPE5.0 interface protocol (PHY INTERFACE For the PCI Express 5.0.0) is correspondingly used, and in the PIPE4.0 interface protocol (PHY INT ERFACE For the PCI Express 4.0.0) corresponding to the original PCIE4.0 interface, signals with a lower strict timing requirement are transmitted through a message_bus (information bus) to match the MAC layer and the PCS layer, and the message_bus (information bus) manages Message transmission from a signal sender to a signal listener (receiver). Therefore, the message_bus can be used for transmitting the signals with lower time sequence requirements between the MAC layer and the PCS layer, so that the message_bus used for transmitting the signals with lower time sequence requirements can be regarded as a register (for example, a receiving and transmitting register with data receiving and data transmitting functions) matched with the MAC layer and the PCS layer, the connection of the MAC layer and the PCS layer is realized, the number of interface signal lines in an interface can be greatly reduced, and the problem of signal crosstalk is solved.

Therefore, in order to use the PIPE5.0 interface of the PCIE VIP (PCIE Verification intellectual property, the intellectual property core used for interface verification) for connecting the PCS layer of the MAC layer core, in the process of chip design, the PIPE4.0 interface of the PCS layer of the MAC layer core in the design under test (Design Under Test, DUT) is converted into the PIPE5.0 interface through the interface bridge, so that the interface of the design under test after conversion is adapted to the PIPE5.0 interface protocol, the converted interface has the performance of reducing the number of interface signal lines in the interface and solving the signal crosstalk problem. The to-be-tested design is a chip design to be tested, and may be a functional hardware used for forming a complete chip design, for example, a bus interface used for forming a cache in the chip design, and when the to-be-tested design is used for forming a bus interface in the chip design, it indicates whether the function of the test bus interface is correct, for example, whether the test bus interface can send data and receive data.

However, whether the conversion function of the interface bridge after the design is completed is correct, that is, whether the interface after the conversion of the interface bridge can be used normally or not is not guaranteed. For example, in the application scenario of PCIE, if the conversion function of the interface bridge pipe_bridge is correct, in other words, if the PIPE4.0 interface is directly converted by using the interface bridge pipe_bridge that is completed in design, whether the converted PIPE interface can be used normally, that is, whether the number of interface signal lines in the interface can be reduced, so that the problem of signal crosstalk is solved is not known. In a further step, if the conversion function of the interface bridge is problematic, errors may occur in the use of the interface after the subsequent conversion, affecting the overall system-on-chip application and design.

Therefore, in order to address the above-mentioned problems or other problems, an embodiment of the present invention provides an interface protocol conversion verification system for verifying the functional correctness of an interface bridge and ensuring that a chip design can be normally linked.

Referring to fig. 2, fig. 2 is a schematic structural diagram of an interface protocol conversion verification system according to an embodiment of the invention; the interface protocol conversion verification system can be applied to a general verification platform, for example.

The universal verification platform is a verification platform built based on universal verification methodology (UVM, universal Verification Methodology) and can be used for performing verification of chip front-end design, and consists of all universal verification components; the general verification methodology is the most popular verification methodology in the current chip verification, in the simulation of the chip and the verification of the chip, UVM instructs the chip verification to start from the actual functional Specification (Specification) of the chip design, make a verification plan, decompose test points, create test cases, define a test acceptance (sign-off) mode and standard, process automation and report automation, and the like. The UVM provides a reusable mechanism of verification environment and test cases in the form of class library, so that the chip verification efficiency is greatly improved.

Therefore, in the built general verification platform, the verification of the chip front end design is completed by using the general verification components, for example, the results of interface protocol conversion of the interface bridge are verified by the included general verification components through the inside of the verification environment of the general verification platform, and the reusability and the verification efficiency of the interface protocol conversion verification system capable of being used for verifying the interface bridge can be improved based on the characteristics of UVM.

As shown in fig. 2, the interface protocol conversion verification system includes:

the interface bridge 1 is configured to convert interface information to be converted into interface information to be verified, where the interface information to be converted is interface information corresponding to an interface protocol to be converted;

The interface information acquisition module 2 is used for acquiring the interface information to be verified and target interface information, wherein the target interface information is interface information corresponding to a target interface protocol;

The verification module 3 is used for verifying whether the interface protocol corresponding to the interface information to be verified is the same as the target interface protocol corresponding to the target interface information, and when the verification result is yes, the interface protocol conversion of the interface bridge is correct; the interface protocol to be converted is different from the target interface protocol.

It should be noted that, the interface information to be verified obtained by the interface information obtaining module 2 may be interface information directly sent by the interface bridge after the interface bridge is converted; or the interface information sent by the converted interface after the interface bridge conversion is completed. That is, the interface information to be verified includes both the interface information acquired in the process that the interface bridge performs the interface protocol conversion and the converted interface is not started to be used, and the interface information acquired in the process that the interface bridge finishes the conversion and the converted interface is started to be used, by using the interface information acquired in the process that the interface does not transmit the transaction layer data packet, the direct verification of the interface protocol conversion function of the interface bridge can be realized, and by using the interface information acquired in the process that the interface starts to transmit the transaction layer data packet, the indirect verification of the interface protocol conversion function of the interface bridge can be realized, thereby fully ensuring the reliability of the verification result.

In the PCIE application example, for example, when the interface bridge 1 is used to convert the PIPE4.0 interface protocol into the PIPE5.0 interface protocol, the PIPE5.0 interface protocol may be the target interface protocol corresponding to the target interface protocol.

Because whether the interface protocol conversion of the interface bridge is correct is not determined, the interface information which is used as interface information to be verified in the converted interface information, the interface information which is used as interface protocol of a conversion target is used as target interface information, and further the interface protocol which is used for verifying the interface information to be verified by using the interface protocol which is used for verifying the interface information by using the verification module 3, whether the interface protocol which is used for verifying the interface information is identical to the target interface protocol of the target interface information is determined, if so, the interface protocol conversion is correct, the interface protocol conversion function of the interface bridge is normal, and the normal operation of the subsequent chip design can be ensured.

Therefore, in the interface protocol conversion verification system provided by the embodiment of the invention, on one hand, the interface protocol conversion verification system comprises the verification module 3 for verifying the interface protocol conversion of the interface bridge and the interface information acquisition module 2, so that the interface information to be verified, which needs to be verified, and the target interface information serving as a verification reference are acquired through the interface information acquisition module 2; therefore, the interface protocol corresponding to the interface information to be verified can be verified based on the target interface protocol corresponding to the target interface information, and when the interface protocols are the same, the interface protocol conversion is correct. The above verification system can verify whether the interface protocol conversion function of the interface bridge 1 is correct, so that the interface after converting the interface protocol can be normally used.

On the other hand, since the interface bridge 1 can determine the changed interface information as the interface information to be converted when any interface information is changed in the interface information sent by the interface corresponding to the interface protocol to be converted, and encode the changed interface information to be converted to obtain the interface information meeting the target interface protocol, the interface protocol to be converted can be directly converted into the target interface protocol; because the interface bridge 1 encodes the changed interface information only when detecting the change of the interface information sent by the interface corresponding to the interface protocol to be converted, the processing amount of the interface information to be converted is less, so that the interface protocol conversion speed of the interface bridge 1 can be faster, the simulation verification time consumption of the interface bridge 1 can be reduced in the verification process, and the verification efficiency of the interface bridge 1 is improved.

When an interface corresponding to another interface protocol different from the current interface protocol is required to be used, the interface bridge 1 can be utilized to rapidly realize the conversion of the two different levels of interface protocols, so that the interface protocol conversion function of the interface bridge 1 can be rapidly verified, and the effect of improving the verification efficiency is achieved; and when verification is successful, the interface corresponding to the target interface protocol meeting the use requirement can be obtained quickly, and the use convenience of the interfaces corresponding to different interface protocols is improved.

In still another aspect, the above-mentioned interface protocol conversion verification system is applied to a general verification platform, specifically, the interface information acquisition module 2 and the verification module 3 in the interface protocol conversion verification system may be some components disposed on the general verification platform, so that the interface protocol conversion verification system may have reusability, and is convenient to use in verification environments corresponding to different types of interface protocol conversion.

Based on the foregoing discussion, it may be known that the interface information to be verified may be obtained when the interface does not send the transaction layer data packet, that is, when the interface bridge 1 just completes interface protocol conversion; or the interface protocol conversion function of the interface bridge 1 can be verified based on different interface information to be verified by acquiring the interface when the interface starts to send the transaction layer data packet after the conversion of the interface bridge 1 is completed. The interface bridge 1 is required to convert the interface information, whether the interface bridge 1 completes the conversion of the interface protocol, and the interface after the conversion is unused, or the interface bridge 1 completes the conversion of the interface protocol, and the converted interface starts the process of use.

Therefore, the embodiment of the present invention is first directed to the verification process of the interface bridge 1 when the interface bridge 1 is used to complete the interface protocol conversion and the two interfaces do not send the transaction layer data packet. In order to realize the function verification of the interface bridge 1, that is, the interface information obtaining module 2 obtains the interface information to be verified for verification, the interface protocol conversion verification system may further include an interface protocol conversion module for realizing the interface protocol conversion of the interface bridge 1. Please continue to refer to fig. 2.

As shown in fig. 2, the interface protocol conversion verification system may further include:

the interface 4 corresponding to the interface protocol to be converted includes a signal sending module 41 to be converted, configured to send an interface protocol signal to be converted to the interface bridge 1, where the interface protocol signal to be converted is a signal forming the interface information to be converted;

The interface 5 corresponding to the target interface protocol includes a target signal sending module 51, configured to send a target interface protocol signal to the interface information obtaining module 2, where the target interface protocol signal is a signal forming the target interface information;

the interface bridge 1 includes an interface protocol conversion module 11, configured to convert the interface protocol signal to be converted to obtain interface information to be verified, which is sent to the interface information obtaining module 2.

It should be noted that, the interface information sent by the signal sending module 41 to be converted and the target signal sending module 51 is an interface protocol signal, where the interface protocol signal is a signal that can be sent by the interface before the transaction layer data packet is not sent.

At this time, the interface information to be verified is interface information formed by the signals converted by the interface protocol signals to be converted, that is, after the interface protocol signals to be converted are converted by the interface protocol conversion module 11, the converted interface protocol signals are obtained, so that information formed based on the converted interface protocol signals is formed. The target interface information is interface information formed by a protocol signal corresponding to the interface protocol to be converted, that is, information formed by the target interface protocol signal sent by the target signal sending module 51.

After the interface bridge 1 finishes the conversion of the interface to be subjected to the interface protocol conversion, and the converted interface is in the unused process, the interface bridge 1 can be directly verified to have correct interface protocol conversion function by verifying the interface information to be verified formed by the converted interface protocol signal, namely by comparing the interface protocol corresponding to the converted interface protocol signal with the interface protocol corresponding to the target interface information formed by the target interface protocol signal, and when the interface protocols are the same, the verification of the interface bridge 1 can be ensured and the verification efficiency of the interface bridge can be accelerated.

In one embodiment, the verification module 3 may be a state machine or may be an interface information parsing verification module.

When the verification module 3 is the state machine, the interface information obtaining module 2 and the verification module 3 may be disposed between the interface module corresponding to the target interface protocol and the interface protocol conversion module 11, that is, outside the interface module corresponding to the target interface protocol and the interface protocol conversion module 11.

In one example, when the verification module 3 is the state machine, the state displayed in the state machine may be used, and when the interface protocol corresponding to the interface information to be verified after conversion is aligned with the target interface protocol corresponding to the target interface information (target interface protocol signal), the interface protocol corresponding to the interface information to be verified after conversion is the same as the target interface protocol, and the interface protocol conversion is correct.

When the interface information obtaining module 2 and the verification module 3 are the interface information analysis verification modules, the interface information analysis verification modules may be located inside the interfaces corresponding to the target interface protocols (as shown in fig. 2), that is, the interface information analysis verification modules may be verification functions that are automatically implemented inside the interfaces 5 corresponding to the target interface protocols, and after the interfaces 5 corresponding to the target interface protocols receive the interface information to be verified, which is converted by the interface protocol conversion module 11, the interface information analysis verification modules inside the interfaces 5 corresponding to the target interface protocols are utilized to analyze the interface information to be verified, and if the interface information to be verified can be analyzed and applied, that is, the interface protocol corresponding to the interface information to be verified after analysis is the same as the target interface protocol, the interface protocol conversion is correct.

By means of the different types of verification modules 3, the interface protocol corresponding to the interface information to be verified can be verified, the interface protocol conversion function of the interface bridge 1 can be fully verified, and the reliability and accuracy of the interface protocol conversion can be enhanced.

The two verification modules 3 of the state machine or the interface information analysis verification module can be used simultaneously so as to fully ensure the reliability of the verification result; of course, the state machine or the interface information analysis verification module may alternatively be used, and in one embodiment, in order to facilitate detection and viewing of the verification result, verification may be performed by using only the state machine; in another embodiment, in order to reduce the number of components set in the verification environment and improve the verification efficiency, the verification may be performed by using only the interface information parsing verification module; selecting the applicable authentication module 3 improves the authentication flexibility based on different authentication requirements.

In other embodiments, the interface protocol conversion function of the interface bridge 1 may also be verified by means of indirect verification. As described above, after the interface bridge 1 finishes the conversion of the interface protocol, and under the condition that the converted interface starts to be used, the interface bridge 1 is indirectly verified to have correct interface protocol conversion function, so as to ensure the verification of the interface bridge and accelerate the verification efficiency of the interface bridge.

In order to sufficiently ensure the reliability of the verification result of the interface protocol conversion function of the interface bridge 1, in one embodiment, when the interface bridge 1 completes the interface protocol conversion and the to-be-converted data packet sending module 41 and the target data packet sending module 51 start to be used to send out the transaction layer data packet, the verification may be performed from the sending directions of the two data packets, so as to ensure the accuracy and the reliability of the verification result.

Firstly, a transaction layer data packet to be converted is sent from an interface 4 corresponding to an interface protocol to be converted, and an example of sending the transaction layer data packet as a target by an interface 5 corresponding to a target interface protocol is described, please refer to fig. 3, fig. 3 is a schematic diagram of another structure of the interface protocol conversion verification system provided by the embodiment of the present invention.

As shown in fig. 3, the interface protocol conversion verification system may further include:

a main data packet conversion module 61, configured to convert a main transaction layer data packet to obtain interface information to be verified, which is sent to the interface information obtaining module 2;

The interface 4 corresponding to the interface protocol to be converted includes a main data packet sending module 42 to be converted, configured to send a main transaction layer data packet to be converted to a main data packet conversion module 61, where the main transaction layer data packet to be converted is a data packet forming the interface information to be converted;

The interface 5 corresponding to the target interface protocol includes a target main data packet sending module 52, configured to send a target main transaction layer data packet to the interface information obtaining module 2, where the target main transaction layer data packet is a data packet forming the target interface information;

the interface bridge 1 comprises:

the main conversion completion information sending module 12 is configured to send out interface protocol conversion completion information to the main data packet sending module 42 to be converted and the target main data packet sending module 52 when the interface protocol conversion module 11 of the interface bridge completes interface protocol conversion.

It should be noted that, because each interface module may include the transaction layer data packet that sends the transaction layer data packet to be converted and the target transaction layer data packet, after the interface bridge 1 finishes interface protocol conversion, in the process that the interface starts to use, corresponding data packet verification may be performed according to the type of the data packet currently sent by the interface; thereby sufficiently verifying the interface protocol conversion function of the interface bridge 1.

The main conversion completion information sending module 12 may be a functional module inside the interface bridge 1, and after the interface bridge 1 completes interface protocol conversion, for example, after the interface protocol conversion module 11 of the interface bridge 1 converts the interface protocol to be converted into the target interface protocol, the main conversion completion information sending module 12 is triggered to send the information that the interface protocol conversion module 11 completes interface protocol conversion to the main data packet sending module 42 to be converted and the target main data packet sending module 52 to enable the main data packet sending module 42 to be converted and the target main data packet sending module 52 to perform sending of the subsequent transaction layer data packet.

That is, the master conversion complete information sending module 12 is a functional module that triggers the master data packet sending module 42 to be converted and the target master data packet sending module 52 to perform subsequent applications.

The main packet conversion module 61 is a module used in the process of starting the main packet transmission module 42 to be converted and the target main packet transmission module 52 after the interface protocol conversion is completed, and may provide the interface information acquisition module 2 with interface information to be verified.

At this time, the interface information to be verified is the interface information formed by the transaction layer data packet converted by the main data packet conversion module 61, and the target interface information is the interface information formed by the target main transaction layer data packet.

By using the main data packet conversion module 61 to obtain the interface information to be verified formed by the converted transaction layer data packet during the use of the main data packet transmission module 42 to be converted and the target main data packet transmission module 52, further verify that the interface protocol corresponding to the converted transaction layer data packet is the same as the target interface protocol corresponding to the target main transaction layer data packet, when the interface protocols are the same, it is indicated that the main data packet transmission module 42 to be converted and the target main data packet transmission module 52 can normally transmit the transaction layer data packet, and indirectly prove that the interface protocol conversion function of the interface bridge 1 is correct.

In one embodiment, to obtain the primary transaction layer data packet to be converted and the target primary transaction layer data packet in real time, a module for obtaining the data packet may be further provided. Please continue to refer to fig. 3.

A main sampling module 71 to be converted, configured to sample the main transaction layer data packet to be converted sent by the main data packet sending module 42 to be converted, so as to obtain a main transaction layer data packet to be converted sent to the main data packet converting module 61;

the target main sampling module 81 is configured to sample the target main transaction layer data packet sent by the target main data packet sending module 52, and send the sampled target main transaction layer data packet to the interface information obtaining module 2;

the primary data packet conversion module 61 is configured to convert the primary transaction layer data packet to be converted to obtain converted interface information to be verified, and includes:

And converting the to-be-converted main transaction layer data packet sampled by the to-be-converted main sampling module 71 to obtain converted to-be-verified interface information.

The main transaction layer data packet to be converted and the target main transaction layer data packet can be timely obtained through the main sampling module 71 (HOST Monitor 1) to be converted and the target main sampling module 81 (HOST Monitor 2) to be converted, so that subsequent verification of the data packet can be rapidly performed.

In another embodiment, to ensure the correctness of the sampled to-be-converted primary transaction layer data packet and the target primary transaction layer data packet, the data packets may also be detected. The interface protocol conversion verification system may further include:

The main detection module to be converted is configured to determine an interface protocol of a main transaction layer data packet to be converted, which is sampled by the main sampling module 71 to be converted, and detect whether the interface protocol is the same as the interface protocol to be converted, if yes, send the main transaction layer data packet to be converted to the main data packet conversion module 61;

The target main detection module is configured to determine an interface protocol of the target main transaction layer data packet sampled by the target main sampling module 81, and detect whether the interface protocol is the same as the target interface protocol, and if yes, send the target main transaction layer data packet to the interface information acquisition module 2.

The slave conversion completion information sending module 13 may be a functional module inside the interface bridge 1, and after the interface bridge 1 completes interface protocol conversion, for example, after the interface protocol conversion module 11 of the interface bridge 1 converts an interface protocol to be converted into a target interface protocol, the slave conversion completion information sending module 13 is triggered to send information that the interface protocol conversion module 11 completes interface protocol conversion to the slave data packet sending module 53 to be converted and the target slave data packet sending module 43, so that the slave data packet sending module 53 to be converted and the target slave data packet sending module 43 may perform sending of a subsequent transaction layer data packet.

That is, the slave conversion complete information transmitting module 13 is a functional module that triggers the slave packet transmitting module 53 to be converted and the target slave packet transmitting module 43 to perform subsequent applications.

The slave packet conversion module 62 is a module used in the process of starting to use the slave packet transmission module 53 to be converted and the target slave packet transmission module 43 after the interface protocol conversion is completed, and may provide interface information to be verified for the interface information obtaining module 2.

Because the data packet of the to-be-converted transaction layer is sent out by the interface 4 corresponding to the target interface protocol, and the data packet of the target transaction layer is sent out by the interface 5 corresponding to the interface protocol of the to-be-converted transaction layer, the data packet of the to-be-converted transaction layer and the data packet of the target transaction layer can be verified through the to-be-converted master detection module and the target master detection module, so that the interface protocol corresponding to the data packet of the to-be-converted transaction layer is ensured to be the same as the interface protocol of the target interface protocol, and meanwhile, the interface protocol corresponding to the data packet of the to-be-converted transaction layer is ensured to be the same as the interface protocol of the to-be-converted interface protocol, and the reliability of the verification result is ensured.
