Abstract: PURPOSE: An emulating method in a switching system is provided to directly find out a main cause of a failure through an emulation process in the switching system without another emulator, so as to quickly find out the main cause. CONSTITUTION: If an 'enter key' is inputted from a PC, a switching system stores an inputted command in a buffer(102). The system decides whether the command is a break command(104). If so, the system uses an address inputted in a decoder to generate an interrupt, when the address is accessed subsequently(108). If the command is not the break command, the system decides whether the inputted command is a trace command(106). If so, the system uses the address of the decoder and sets up a trace flag of an optional buffer in a RAM, to present the trace command, then returns to a step of deciding whether the 'enter key' is inputted(100). If the command is not the trace command, the system decides whether the inputted command is a display command(112). If so, the system outputs an inputted address or a CPU register to a display, and returns to the step of deciding whether the 'enter key' is inputted. If the command is not the display command, the system displays an error message on the display and returns to the step of deciding whether the 'enter key' is inputted(116).
