A hardware-software co-simulator for embedded system design and debugging

One of the interesting problems in hardware-software co-design is that of debugging embedded software in conjunction with hardware. Currently, most software designers wait until a working hardware prototype is available before debugging software. Bugs discovered in hardware during the software debugging phase require re-design and re-fabrication, thereby not only delaying the project but also increasing cost. It also puts software debugging on hold until a new hardware prototype is available. In this paper we describe a hardware-software co-simulator that can be used in the design, debugging and verification of embedded systems. This tool contains simulators for different parts of the system and a backplane which is used to integrate the simulators. This enables us to simulate hardware, software and their interaction efficiently. We also address the problem of simulation speed. Currently, the more accurate (in terms of timing) the models used, the longer it takes to simulate a syste...
