Emulator environment based on an FPGA prototyping board

We describe an emulator environment based on an FPGA prototyping board. This emulator environment is for functional verification of a multimedia processor we are developing and for software development and debugging of its application programs. For these purposes, the emulator environment includes a debugging network and provides virtual wires and some utilities, board control functions, and a virtual FPGA board. With this environment we verify the functionality of a multimedia processor and implements its cycle level simulator.
