Hardware verification is typically the bottleneck of the chip development cycle, mainly due to the time-consuming simulation and debugging process using software simulators. Assertion-Based Verification (ABV) has been widely adopted to provide better visibility into microarchitecture details and automatically detect unexpected behaviors. While ABV significantly improves verification efficiency, checking assertions using software simulators requires extremely long times for large benchmarks. Prototyping designs on an FPGA is a potential alternative to verify hardware, but it lacks fine-grained debugging capabilities for when errors occur.
