PROBLEM TO BE SOLVED: To verify a microcomputer program even when a target does not exist and even when a target does not operate normally. SOLUTION: A signal inputting part 14 and a signal outputting part 15 are provided at the connection part of a microcomputer 8 and a target part 3. A debugger 4 controls the part 15 from a signal of the connecting part which is inputted from the part 14 or the access of computer 8 to an emulation memory 9 and verifies a microcomputer program by giving a signal to the microcomputer instead of a peripheral circuit part 10 on the part 3 that does not operate normally. |
