Fast development of source-level debugging system using hardware emulation

We describe the co-development of a processor and its source-level debugging system using an emulation-based validation technology including hardware emulation, not simulation, Since a source-level debugging system is essential to develop an application system and it takes a long time to validate the functionality of the source-level debugging system, we have adopted hardware emulation for a fast validation and system development. Using this methodology, we were able to validate the source-level debugging system successfully before the chip fabrication.
