Abstract

PURPOSE:To easily judge how a test program needs to be reinforced by executing the test program under device simulation. CONSTITUTION:A simulation control part 4 reads an instruction word out of a test program storage part 5 and refers to an instruction-function conversion table 2 to determine in what order respective functions for executing the instruction are put in operation. Then the simulation control part 4 indicates the execution of simulation to a function simulation part 1 according to the determined execution order of the function parts. Further, the simulation control part 4 registers which function is used for which instruction in an execution history storage part 3 every time when each function is simulated. Thus, which function of which instruction is used, and which function of which instruction is not used are easily and accurately decided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an evaluation method for test programs for electronic computers.

[Conventional technology]

When developing electronic computers, it is common to develop and use test programs for the purpose of design evaluation, and for the purpose of maintaining computers in use for business purposes.

The developed test program passes evaluation using various evaluation items and is completed as a final test program.
As part of this evaluation, there is an evaluation to confirm that the test program tests all the functions targeted for testing. Conventionally, this type of testing has relied on manual labor, in which a person compares the specifications of the device to be tested with the test program specifications and makes a decision.

[Problem to be solved by the invention]

However, the above-mentioned conventional manual confirmation not only requires a great deal of effort, but also has the disadvantage that evaluation omissions are likely to occur.

[Means to solve the problem]

The test program evaluation method of the present invention includes a simulation means for simulating the operation of the device under test;
The simulation means includes an execution history storage means for storing whether or not each function constituting the simulation means has been used, and means for displaying the contents of the execution history storage means.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows a device simulation that is an embodiment of the present invention, and includes a function simulation section 1 that simulates each function that realizes the operation of the test target device, and a function simulation section 1 that simulates each function that realizes the operation of the test target device, and an instruction/function change table 2 that stores the order in which the functions are executed, an execution history storage section 3 that stores whether the functions of the simulation section 1 are used for each instruction; It is composed of a simulation control section 4 that controls the simulation operation of the device simulation, a test program storage section 5 that stores the test program for the device under test, and a control console 6 that provides an interface with the operator.

Next, the operation of this device simulator will be explained.

First, the operator instructs the simulation control section 4 to erase the memory of the execution history storage section 3 via the control console 6. Then, the simulation control section 4
erases the memory in the execution history storage section 3. Subsequently, the operator instructs the simulation control section 4 to start the test via the control console 6.

The simulation control unit 4, which has been instructed to start the test, retrieves the instruction word from the test program storage unit 5, refers to the instruction/function conversion table 2, and determines in what order each function to realize the instruction should be executed. . Next, the simulation control unit 4 instructs the function simulation unit 1 to execute the simulation according to the previously determined function execution order. Further, the simulation control unit 4 registers which command used which function in the execution history storage unit 3 each time each function simulation is completed.

After completing the test program by sequentially executing the commands, the operator can use the control console 6 to
The simulation control unit 4 is instructed to output the contents stored in the execution history storage unit 3. The simulation control unit 4 reads out the contents of the execution history storage unit 3 and displays on the control console 6 which function is used for each command.

〔Effect of the invention〕

As explained above, by executing a test program on a device simulation, the present invention can easily and easily determine which functions of which instructions are used and, conversely, which functions of which instructions are not used. This has the effect of making it possible to make accurate determinations and therefore making it easy to judge how to strengthen the test program. Furthermore, it also has the effect of making it easy to re-evaluate a strengthened test program.
