Despite their wide use in digital and embedded systems, Field-Programmable Gate Array (FPGA) debugging remains challenging due to design complexity, limited observability, and inefficient trace analysis. The field still lacks a standard benchmark. This makes it hard for researchers to compare their work or verify what has already been done in FPGA debugging. We present a benchmark for FPGA debugging that includes typical bug cases, various fault types, configurable observability settings, and Integrated Logic Analyzer (ILA)-based reference baselines. The benchmark supports consistent and reproducible evaluation of FPGA debug systems and tools. It reduces the difficulty of FPGA debugging research and facilitates systematic comparison, reproducibility, and innovation in FPGA debugging system development.
