ABSTRACT:
A debugging apparatus is disclosed which verifies a program to be embedded into a target machine by running the program in an environment which is one or the target machine, an emulator, and a simulator. Each environment includes operation state information of the program and inputs and outputs the operation state information in a form unique to the environment. The debugging apparatus includes; target environment storing unit for storing an identification name of the target environment; receiving unit for receiving a command from an operator; instruction detecting unit for detecting a certain instruction in the command; specifying unit for, when the certain instruction is detected, specifying a target environment specified by the identification name as a source target environment and for specifying any of the rest of the environments as a destination target environment; reading unit for reading operation state information from the source target environment; converting unit for converting the operation state information into operation state information written in a form unique to the destination target environment; setting unit for setting the converted operation state information in the destination target environment; and operation resuming unit for resuming the operation of the program in the destination target environment.
