Associated apparatus and method for supporting development of semiconductor device

An associated development-support apparatus for a semiconductor device enables highly accurate debugging and verification of operations. An emulator stub acquires event information by using a communication control unit, where the event is generated in a debugger, the event information is generated by a debugger stub according to an event, and transmitted by the debugger stub through a communication network. An emulator control unit analyzes the acquired event information, and controls an emulator according to the analyzed event so as to perform emulation processing which virtually emulates operations of the semiconductor device corresponding to the event based on hardware design information. The emulator stub acquires results of the event which is generated in association with the operations of the semiconductor device virtually emulated by the emulator, and notifies the debugger of the results of the event through the communication network and the debugger stub.
