Chipyard supports two classes of simulation:
- Software RTL simulation using commercial or open-source (Verilator) RTL simulators
- FPGA-accelerated full-system simulation using FireSim
Software RTL simulators of Chipyard designs run at O(1 KHz), but compile quickly and provide full waveforms. Conversly, FPGA-accelerated simulators run at O(100 MHz), making them appropriate for booting an operating system and running a complete workload, but have multi-hour compile times and poorer debug visability.
