A system and a method for analyzing failures, and an emulator thereof are provided to register break points in a program irrespective of the number of break point registers provided from a target device, such as a CPU, and obtain a plurality of events while the events are traced in the program operated in a ROM of the target device. An event tracer traces the event of the program executed in a target device(300). The target device has a debugging function including an event tracing function, a memory storing the program, and a CPU executing the program. An ICE(In-Circuit Emulator)(200) is connected to the CPU of the target device through an interface, and includes a CPU debugging function and a CPU control function for controlling the CPU through the interface. A host computer(100) includes a debugger(110) having an emulation control function associable with the emulator. The CPU control function has a function for issuing and outputting a forcible CPU break signal to the CPU of the target device. The CPU has the function for forcibly breaking operation executed at the inside by the forcible CPU break signal.
