Checkpointing in an emulation system

摘要

A method and apparatus for outputting a current state of a real-time circuit emulator. When the emulator is set to a predetermined state, it checkpoints the contents of certain memory and registers at the time it enters the predetermined state. The output of the emulator can be used as input to the emulator or as input to another system, such as a simulator, which does not operate in real-time. If the simulator also generates an output having same format, the output of the simulator can also be input to the real-time emulator.
