CONSTITUTION:A defining device 4 is connected between an input device 2 and a processor 1 of a simulator, and the device 4 is provided with a memory storing information defined at each phase of a program of debug objective. The program being the debug objective is executed on simulation basis at the processor 1 and the result of processing of the program is outputted to an output device 3. At the end of each phase of the program, the processor 1 compares the result of execution with the information stored in the device 4 in advance, and a bug is forcedly corrected and the presence of the bug is informed to the device 3, the program is advanced and the efficiency of debugging is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a simulation device used for debugging a program of a data processing device.

Conventionally, there was a device for this woodcutter as shown in FIG.

In FIG. 1, there is a device equipped with a processing device 1 having a built-in memory, an input device 2, and an output device 3. When debugging a program using this simulation device, the program to be debugged is first stored in the memory of the processing device 1 via the input device 2. Next, an execution instruction is given to the processing device 1, and the program is executed on a simulation basis. Various information, processing results, etc. in the processing process of the program are appropriately output to the output device 3 and displayed. A program debugger reads the information displayed on the output device 3, and when a bug is detected, analyzes the cause and proceeds with the debugging work.

Conventional simulators are configured as described above, so debuggers must have sufficient knowledge of the program to be debugged and its design algorithm, and if there is a bug in the program, unless it is removed,
Even if the process progresses, it becomes meaningless, so debugging has to be performed each time, which has the disadvantage of poor efficiency in emergency pressure. This invention eliminates the above-mentioned disadvantages of the conventional method. Therefore, at the end of each phase of the 10 grams to be debugged, the execution result is compared with the information defined by the definition device, and if no match is found, it is an error indicating the existence of an enemy bag. To provide a simulation device that can efficiently execute debugging work by outputting detected information to an output device, replacing erroneous execution results with correct information from a definition device, and proceeding with debugging of the above program. The purpose is to

An embodiment of the present invention will be described below with reference to the drawings. Second
In the figure, a definition device 4 having a memory that stores information to be defined for each phase of a program to be debugged is connected between an input device 2 and a processing device 1. Other parts are the same as those in FIG.

Here, the memory of the processing device 1 stores information by forming a memory map as shown in FIG. In FIG. 3, from the top, area A is a management program, area B is a simulator program, area C is a program to be debugged, and area C is an area for storing work data of the program in area C.

The memory of the definition device 4 forms a memory pin as shown in FIG. 4 and stores information. In Figure 4,
From top to bottom, area E is a management program, area F is a list of information defining input/output conditions, and area G is an area for storing input/output data.

The following table is a format diagram describing the program specifications of the simulator of the present invention.

Next, the operation will be explained with reference to FIG. When the processing device 1 and definition device 4 are started, they sequentially execute processing according to their respective memory management programs. That is, in process 5, the input command is analyzed.

In decision 6, it is determined whether the command is simulated.

If the answer is no (N), another process T unrelated to the operation of the present invention is executed; if the answer is yes (Y), the process 8 requests the definition device 4 to send input/output definition information. Execute. On the other hand, after initialization in process 9, definition device 4 waits in judgment 10 to receive a request in process 8 from processing device 1, and when it receives this, it executes process 11 to read input/output definition information from its memory. It is determined whether this information is an end code or not in a judgment 12. If the answer is yes, the debugging process is ended, and if the answer is no, the input/output definition information is sent to the processing device 1.

Upon receiving the input/output definition information, the processing device 1 makes a decision 14.
is extracted, and in judgment 14 it is judged whether or not it is finished. If YES, memory area DK input/output definition information is set.

In process 17, the process of phase n is executed, and it is determined whether the execution result matches the input/output definition information 18
If the answer is yes, the process returns to process 8, and if the answer is no, error detection information indicating the existence of the bag is output to the output device gII13 in process 19, and then in process 20, the process returns to step n.
After updating the processing result with the biased input/output data, the process returns to process 8. In other words, even if there is a bag, 10
The processing of phase n is completed using the input/output definition information read from the definition device 4 without causing the program to become stagnant, and it is possible to proceed to the debugging work of the next phase n+1.

In the above embodiment, the definition information provided by the definition device to the processing device for each phase is in a batch processing format, but it may also be in a conversation format, and the same effects as in the above embodiment can be achieved.

As mentioned above, according to the present invention, even if there is a bug in the program, it is forcibly corrected, and the existence is notified to the outside so that the program can proceed, making debugging work more efficient. can increase
