Description

The invention relates to computational and medical technology and can be used to test multi-contact logic electronic circuits, as well as to study neural ensembles in an electrophysiological experiment, the program of which is compiled in advance in the process of modeling the objects of study on an electronic computer.

A device for carrying out tests containing a computer and an interaction apparatus (stimulators and registrars) with the test object is known. A computer using a program that is the same for each type of object under study, controls stimulation (by applying effects to the inputs of the object) and recording the output signals of the test object. In the control of electronic circuits of a computer, the recorded parameters are compared with the reference (model) stored in the computer memory, and determines the suitability of the test device 1.

The disadvantage of this device is its high cost, which adds up to the cost of the equipment, which includes a computer with the appropriate interface equipment / and a huge amount of expensive machine time, since the computer is fully loaded for the entire test period, which can be very long , when checking devices for endurance.

The closest to the proposed technical entity is a device that contains a block of primary equipment for recording and stimulating an object. Two tape drives, an analog-to-digital converter, a trigger, a control unit, an analog signal switch, a logical signal switch, digital-analog converter, logic stimulus registers, a three-digit ring shift register, a register of address registers and a stimulation field address elements AND, OR, valve block two registers and two decoders 21.

Object testing is carried out in three stages. With the help of a computer, a program for stimulation and data recording is developed, which is recorded onto a standard magnetic tape by zones of optimal length and density of recording. The zone is filled with a set of three-byte control layers. The first byte of each control word contains the address of the registration floor, the second byte of the address of the stimulation field, and the third data of the stimulus. One of the tracks of the control magnetic tape (ML) is filled with blocks of single information and serves to synchronize the recording and copy the data placement formats from the control ML on the ML registration, which ensures the compatibility of the latter with the computer and its subsequent processing.

Before testing, the control ML is transferred to an automatic test device and installed on the first drive. On the second drive, set the ML for registration. The electrode is connected to analogue and logical inputs and outputs of the test object according to the address table issued by the computer when forming the test program.

Magnetic tapes on both drives are brought to the physical marker of the beginning of the tape and are tested using a device.

Test results are recorded on the ML in a convenient form for processing on a computer in batch mode. 5. Final processing is carried out in batch mode on a computer, where, after the Test, ML are transferred with registration data. The computer analyzes the test data, for example, comparing it with the d reference, determines the conformity of the test object model (in the simplest case, determines the suitability of the electronic circuit).

The disadvantages of this device are its complexity (two accumulators are used, processing multistage), and the inability to quickly determine the compliance of the test object with the reference (K 0 models) The purpose of the invention is to reduce the equipment and improve the usability.

In addition to the TOR, the zone-end detection unit contains two triggers and a square pulse generator, the output of which is connected to the first input of the first trigger, the zero output of which is connected to its second. RyoM entrance, a single output connected to the first input cm of the second trigger, the second input of which is connected to the zero potential bus, zero output of the second trigger is the output of the block, the installation inputs of the first and second trigger on the block input. FIG. 1 is a block diagram of the device; in fig. 2 is a block diagram of the end zone detection. The device contains a stimulation signal generator 1, a magnetic tape drive 2, a buffer register 3, a stimulation field address register 4, a stimulation field register 5, a stimulus character register 6, an OR element 7, 8 9 address decoders, a switch 10, a circular shift register 11, registers 12 and 13 of comparison circuit 14, non-offset counter 15, zone end detection unit 16, zone counter 17, results block 18, rectangular pulse generator 19, triggers 20 and 21. The device operates as follows. The testing of objects is carried out in two stages. First, at the stage of modeling an object on a computer, a program of stimulation and data recording is compiled, which is recorded onto a standard magnetic tape by zones of optimal length and density of recording. Each zone consists of four byte control words that respond to one test model or micromodel. The first byte of each control word contains the expected (model) information, the second address of the registration field, the third one, the address of the stimulation field, the fourth, the character of the stimulation. During the tests, the ML is mounted on accumulator 2 and set in motion. This model information is compared with the experimental one that was actually obtained during registration. In case of non-comparison, the content of the counter of non-comparisons is increased by one. Upon completion of the ML, the number of the zone and the number of incomparisons, characterizing the degree of coincidence of the object and its micromodel, implemented by this zone, are received and recorded in block 18 of the output of the results (tests). During the test, the device operates as follows. The signals from the information outputs of the accumulator 2 through the buffer register 3 are fed to the information inputs of registers 4, 5, 6/12 and 13, as well as to the inputs of element 7 OR. From the output of element 7 OR, the signal arrives at the input of the zone end detection unit 16 and the input of the ring shift register 11, the right shift unit there (the power shift register 11 is set to the state. The signals from the register outputs 11 1000, 0100 go to the ports entering information into registers 13, 12, 5 and 4, respectively, and the signal 0001 is fed to the input of the counter 15 and cannot be compared through the decoder 8 to the inputs of the registers 6 of the stimulus pattern. The information from the outputs of the registers 5 and 4 goes to the inputs of the decoders 8 and 9 determined according Stimulus and registration field addresses. At the inputs of generator 1, information signals come from the outputs of the registrars of the character 6, while from the outputs of the generator 1 the experimental information goes to the information inputs of the switch 10, to the control inputs of which the signals come from the output of the address decoder 9. The experimental information from the outputs of the switch 10 is fed through the register 12 to the comparison circuit 14. The same circuit 14 receives information from the output of the register 13. The signal from the output of the circuit 14 of the comparison arrives at the input of the counter 15.

Thus, the first byte of the control tin containing the model information (the expected information is recorded in the register 13 / the second containing the address of the registration field, is written in the register 5 and the experimental (actual) information is also recorded in the register 12; the third byte is written in the register 4; the fourth byte is in one of the 8 registers selected by the decoder B. In the fourth byte, the counter 15 also compares incomparisons. The signal from the output of the zone end detection unit 16 goes to the zone counter 17 and the test output block 18 nah) Since the inputs of block 18 receive information from the outputs of counters 15 and 17, at the end of each zone the number of this zone and the number of discrepancies, the experimental data with the expected ones are recorded.

The end zone detection unit 16 operates as follows.

The generator 19 generates rectangular, symmetrical ig-pulses with a frequency of 200 Hz, which are fed to the input of the trigger 20. At the installation inputs of the flip-flops 20 and 21, tracking pulses are generated, which are produced by the element 7 OR, when reading any byte inside the information zone on the magnetic tape . In the absence of these pulses at the input of the zone end detecting unit 16 (the magnetic tape does not move or when the tape moves, the magnetic head is in the region of the interband gap) flip-flop 0 is thrown and when the trigger 20 goes from the state O to

positive signal

state

from the single output of the trigger 20 enters the input (which is triggered from the positive front) of the trigger 21, and since one of the inputs of the trigger 21 is permanently connected to the zero potential bus (ground), resets it to the zero state if trigger 21 was not already in This state is on power up. In both cases, the positive potential from the zero output of flip-flop 21 enters the zone 17 counter and block 18, indicating that there is no readable information. When under the magnetic head

. passes the information zone recorded on the ML, from the output of the element 7 OR impulses arrive at the installation inputs of the flip-flops 20 and 21. In this case, both triggers are set to one state by the first zone pulse. When a pulse arrives at the input of the trigger 20 from the output of the generator 19, the trigger 20 is transferred to the zero state, producing a negative differential at the single output of the trigger 20. This negative differential arriving at the input (triggered by a positive differential / three 21, does not change its state neither

5 Another playback tracking pulse from the output of element 7 OR is fed to the trigger inputs 20 and 21 and sets the trigger 20 to one state, causing a positive

Q difference at the input of the trigger 21. However, the state of the trigger 21 does not change, since a little earlier (at the flip time of the flip-flop) its input input received a pulse followed by the NIN from the output of element 7 OR with a duration sufficient to prevent the flip-flop of the trigger 21 to the zero state and maintaining zero potential at zero trigger output

21. The zero potential at the output of the zone end detection unit 16 appears with the first playback tracking pulse and remains until the end of the zone, signaling the presence of read information.

5 After the end of the zone, the second pulse from the output of the oscillator 9, by triggering trigger 30 on the counting input to one, ensures that trigger 21 is reset to the zero state, indicating that the end of the zone has been detected. This step occurs 10–20 ms after the termination of the zone on the ML. At the same time, the moving part of the ML passes about 1 / 4-1 / 3 part of the inter-zone zone. It is at this moment that the counting of zones and the registration of the zone number and the number of discrepancies occur.

Q In the proposed device, the equipment is reduced (only one tape drive is used), the machine time is saved and the efficiency is increased due to the possibility to compare the actually recorded parameters of the object with the parameters obtained during the simulation of the object on the computer during tests
