DEBUGGING SYSTEM, EMULATOR, AND DEBUGGING METHOD

摘要

A debug system includes: a microcomputer mounted on a target system; an emulator configured to execute emulation of the microcomputer based on a user program embedded in the microcomputer; and a computer connected with the emulator in radio communication and configured to instruct start of the emulation and to execute a debugging operation of the microcomputer based on a result of the emulation. The emulator includes: a control section configured to execute the emulation of the microcomputer based on control data from the computer; a radio communication state monitoring section configured to monitor a state of the radio communication between the computer and the emulator when the emulation is performed; and a storage section configured to store substitution control data. The control section acquires the substitution control data from the storage section, when the radio communication is in a non-communicable state, and controls the microcomputer based on the substitution control data such that the target system is set to a predetermined state.
