DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of an integrated circuit joint development system and its management server according to the present invention will be described below with reference to the drawings.
[0027]
The integrated circuit joint development system of the present invention is a system for a customer to jointly develop an IC with an information provider based on development information necessary for developing an IC provided by the information provider. As shown in FIG. 2, a management server 1 under the control of an information provider and a plurality of terminal devices 2a, 2b,... 2n under the control of a customer are connected via a communication line 3.
[0028]
Here, the information provider refers to a person who provides design data such as process data and cell data necessary for IC development and manufacturing, such as an IC manufacturer. A customer is a person (user) who develops and designs an IC based on design data provided by the information provider.
[0029]
As shown in FIG. 1, the management server 1 includes at least a management control unit 11, an input device 12, a display device 13, a communication device 14, a process data file 15, a cell data file 16, and a management file 17. ing.
[0030]
The management control unit 11 performs various processes as described later according to a predetermined procedure, and includes a CPU and the like. Each procedure described above is written in advance in a ROM (not shown).
[0031]
The input device 12 is used to input various types of data and includes a keyboard or the like. The display device 13 is used for monitoring input data and the like, and includes a CRT, a liquid crystal display, and the like.
[0032]
The communication device 14 communicates with the terminal devices 2a, 2b,... 2n through a communication line 3 such as a telephone line or a dedicated line.
[0033]
The process data file 15 stores (accumulates) various process data necessary for IC development / design according to a specific order, and includes a storage device such as a semiconductor memory or a hard disk.
[0034]
The cell data file 16 stores cell data related to cells developed by an information provider (IC manufacturer) or a customer as described later in a specific order based on the process data stored in the process data file 15. And is composed of a storage device.
[0035]
Here, the cell refers to a single or a plurality of gates or flip-flops, or a circuit that realizes a specific function using these, and includes not only a digital circuit but also an analog circuit.
[0036]
The management file 17 stores customer-specific billing data related to the use of design data, manufacturing costs for manufacturing ICs designed and developed by customers, customer-specific passwords, etc., obtained by processing as described below. It consists of a storage device. An example of the configuration of the management file 17 is shown in FIG.
[0037]
The plurality of terminal devices 2a, 2b,... 2n are a communication device 21 for communicating with the management server 1 via the communication line 3, an input device (not shown) for inputting data, and an output device for outputting data. (Not shown) and the like, and as described later, the communication device 21 is used to exchange data with the management server 1.
[0038]
Next, an operation example of the integrated circuit joint development system according to the present embodiment having such a configuration will be described.
[0039]
First, a case where design data such as process data and cell data managed by the management server 1 is provided to a customer according to access from the customer will be described with reference to FIGS.
[0040]
For example, when a customer instructs an access request for design data by operating the terminal device 2a, the access request instruction is transmitted by the communication device 21 (step S1).
[0041]
When the communication device 14 of the management server 1 receives the access request (step S2), the communication device 14 transmits a password request to the terminal device 2a according to an instruction from the management control unit 11 (step S3). The communication device 21 of the terminal device 2a receives the password request (step S4).
[0042]
When the customer inputs a password from the terminal device 2a, the password is transmitted by the communication device 21 (step S5). When the communication device 14 of the management server 1 receives the password, the management control unit 11 determines the validity of the access request based on the received password (step S6).
[0043]
If the access is valid as a result of this determination, the management control unit 11 transmits the service content of the management server 1 to the terminal device 2a (step S7). The contents of the service are, for example, process data stored in the process data file 15 or cell data stored in the cell data file 16, that is, an outline of each content of design data.
[0044]
When the communication device 21 of the terminal device 2a receives the service content (step S8), the received service content is displayed on the display screen. When the customer designates design data that the user wants to acquire based on the service contents in the terminal device 2a, the designated design data is transmitted by the communication device 21 (step S9). The designated design data is received by the communication device 14 of the management server 1 (step S10).
[0045]
When receiving the designated design data, the management control unit 11 of the management server 1 reads the contents of the designated design data from the process data file 15 or the cell data file 16 and reads the read design data. It transmits to the terminal device 2a (step S11).
[0046]
When the communication device 21 of the terminal device 2a receives the design data (step S12), the received design data is stored in a storage device (not shown). And each process of step S9-step S12 is performed until acquisition of the design data which a customer requires is completed.
[0047]
Thereafter, when the customer gives an instruction to end the service using the terminal device 2a, this instruction is transmitted by the communication device 21 (step S13). The service termination instruction is received by the communication device 14 of the management server 1 (step S14).
[0048]
Upon receiving the service termination instruction, the management control unit 11 calculates the current usage fee (usage fee) of the design data designated by the customer (step S15). Next, the current usage fee is added to the previous usage fee stored in the management file 17 (step S16), and the usage fee of the management file 17 is updated to the added usage fee (step S17). .
[0049]
It should be noted that the usage fee for the design data of each customer stored in the management file 17 is periodically notified to the terminal devices 2a, 2b to 2n at a predetermined time such as the end of the month. preferable.
[0050]
By such an operation, when designing and developing an IC, the customer can obtain necessary design data such as process data and cell data by accessing the management server 1 at any time. Then, the customer designs and develops the IC based on the acquired design data. At this time, the customer can develop a new cell optimum for his IC on the process data provided by the IC manufacturer. .
[0051]
Therefore, in the integrated circuit joint development system according to this embodiment, cell data related to a cell developed by the customer is registered in the cell data file 16 of the management server 1, and the cell data is used by other customers. An example of the registration of the cell data will be described with reference to FIG.
[0052]
For example, when a customer makes a registration request for development cell data relating to a newly developed cell to the management server 1 by operating the terminal device 2b, the registration request is transmitted by the communication device 21 (step S21).
[0053]
When the communication device 14 of the management server 1 receives the registration request (step S22), the communication device 14 transmits a password request to the terminal device 2b according to an instruction from the management control unit 11 (step S23). The communication device 21 of the terminal device 2b receives the password request (step S24).
[0054]
When the customer inputs a password from the terminal device 2b, the password is transmitted by the communication device 21 (step S25). When the communication device 14 of the management server 1 receives the password, the management control unit 11 determines the validity of the registration request based on the received password (step S26).
If the registration request is valid, the management control unit 11 requests the terminal device 2b to transmit development cell data to be registered (step S27). This request is received by the communication device 21 (step S28). In response to reception of this request, when the customer instructs transmission of the development cell data by operating the terminal device 2b, the development cell data is transmitted by the communication device 21 (step S29).
[0055]
The communication device 14 of the management server 1 receives the development cell data (step S30). The management control unit 11 registers the received development cell data in the cell data file 16 (step S31).
[0056]
Note that after the customer development cell data is registered in the cell data file 16, the usage fee of the design data calculated in step S15 in FIG. 3 includes not only the IC manufacturer but also the customer. There is a case. Accordingly, when calculating the usage fee, the calculation of the usage fee is separately performed for the IC manufacturer and the customer.
[0057]
By the way, the customer can easily obtain design data such as process data and cell data necessary for IC design / development by accessing the management server 1 as described above, and the desired data can be obtained based on the obtained design data. ICs are designed and developed and manufactured under the IC manufacturer.
[0058]
In this case, when calculating the manufacturing cost of the IC, it is necessary to appropriately evaluate the contribution degree between the customer and the IC manufacturer, and to calculate the manufacturing cost based on the evaluation, and the integrated circuit according to this embodiment This joint development system has this function. Therefore, an example of evaluation / calculation of the manufacturing cost will be described with reference to FIG.
[0059]
For example, when the customer instructs the management server 1 to evaluate / calculate the manufacturing cost of the IC to be manufactured by operating the terminal device 2b, the instruction is transmitted by the communication device 21 (step S41). .
[0060]
When the communication device 14 of the management server 1 receives the instruction for evaluation / calculation (step S42), the communication device 14 transmits a password request to the terminal device 2b according to the instruction of the management control unit 11 (step S43). ). The communication device 21 of the terminal device 2b receives the password request (step S44).
[0061]
When the customer inputs a password from the terminal device 2b, the password is transmitted by the communication device 21 (step S45). When the communication device 14 of the management server 1 receives the password, the management control unit 11 determines the validity of the evaluation / calculation instruction based on the received password (step S46).
[0062]
If the instruction is valid, the management control unit 11 requests the terminal device 2b to send a designation of an IC to be evaluated / calculated (step S47). This request is received by the communication device 21 (step S48). In response to this reception, when the customer designates an IC to be evaluated / calculated by operating the terminal device 2b, the designation is transmitted by the communication device 21 (step S49). The communication device 14 of the management server 1 receives the designation (Step S50).
[0063]
When the designated IC is designed and developed, the management control unit 11 evaluates the degree of contribution since the IC manufacturer and the customer contribute to the IC (step S51). In this evaluation, the evaluation data stored in advance in the management file 17 is read out.
[0064]
Here, an example of the evaluation data is as follows. That is, the IC to be evaluated is composed of, for example, 10 cells, of which 4 cells are provided by the IC manufacturer, and the remaining 6 cells are developed by the customer. In this case, each of these data is registered in the management file 17 by the input device 12, for example.
[0065]
In this case, when the use value of each cell is different, for example, it is preferable to assign a score to each cell according to the use value. In this way, when evaluating the degree of contribution, the sum of the scores of each cell of the IC manufacturer and the sum of the scores of each cell developed by the customer are obtained, and both are calculated based on the obtained sum of both. Can be evaluated.
[0066]
Next, the manufacturing cost required for manufacturing the IC is calculated based on the contributions of the IC manufacturer and the customer obtained in step S51 and the cost required for actually manufacturing the IC (step S52). The calculation of the manufacturing cost may be a cost per IC, or may be a cost of all (total) ICs to be manufactured.
[0067]
The calculated evaluation cost of the IC is transmitted by the communication device 14 together with the evaluation data and the like (step S53). After being received by the communication device 21 of the terminal device 2b (step S54), they are displayed on the display screen and stored in the storage device as necessary.
[0068]
As described above, after the customer development cell data is registered in the cell data file 16, the IC manufacturing cost calculated in step S52 in FIG. May be included. Accordingly, when calculating the manufacturing cost of the IC, the IC manufacturer and the customer are separately calculated.
[0069]
As described above, according to the integrated circuit joint development system according to this embodiment, many customers can use the design data related to the joint development of the IC, and the IC manufacturer charges a fee according to the amount of use of the data. Collect fairly and reliably from customers.
[0070]
Also, according to the integrated circuit joint development system according to this embodiment, when a customer develops and designs an IC using design data prepared by an IC manufacturer and develops a new cell at that time, The developed cell data related to the cell can be provided to other customers together with the design data prepared by the IC manufacturer, and the customer who has developed the cell can obtain the usage fee for the cell.
[0071]
Furthermore, according to the integrated circuit joint development system according to this embodiment, when an IC manufacturer manufactures an IC developed by a customer using design data of the IC manufacturer, each contribution degree of the IC manufacturer and the customer is considered. Thus, the manufacturing cost of the IC can be calculated appropriately.
