(Problem to be Solved by the Invention) However, in the conventional debugging method described above, when a program module of a library is referenced during debugging, it is necessary to check the parameters to be passed to the program module and to check the parameters passed to the program module. It is difficult for the user to check the number of times that has been called and to check the simulation when performing hardware operations, and this debugging method using a debugger has the problem that it is difficult to perform debugging operations efficiently. There is.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a debugging device that allows a user to easily check the debugging operation of a program and the status of the debugging operation, and allows the debugging operation to be performed efficiently.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above problems, the present invention provides a program having a plurality of program modules that simulates a predetermined operation when debugging a predetermined program. a group of modules, a group of state management tables ε for managing state information associated with simulated operations of these program modules, and a group of state management tables ε for controlling the execution of simulated operations by the program modules with reference to the state information of the group of state management tables; The apparatus also includes an execution control section that outputs state information of the state management table group based on input from the outside.

(Function) In the present invention, the execution of the debugging simulation operation by the program module is controlled by referring to the state information of the state management table group, and the state information of the state management table group is outputted by external human power. Therefore, the user can easily check the debugging operation of the program and the status of the debugging operation, and the debugging operation can be performed efficiently.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

Status information such as the number of program module calls, parameter status, and execution program module information are written and managed in conjunction with debugging operations.

The execution control unit 24 controls the execution of each program module R, W, .

In addition, the status information associated with the debug operation is output to the display section 25, and when a command is issued from the human power section 26, each program module R, W...S in the debug operation is controlled based on the command. Control execution.

In the debug device configured in this way, when the Read program module R of the program module group 22 is referenced from the file system access program 27, for example, each state of the state management table group 23 is written, and after that, A Read operation is performed. At this time, if it is a cross environment, the parts that access the hardware are simulated.
