AutoEval-ECov (Direct Inference): leaderboard
Metric: Coverage pass rate (%): share of the 156 problems of AutoEval-ECov (VerilogEval turned into testbench coverage tasks following CorrectBench, golden RTL and specification given) for which the model's SystemVerilog testbench reaches 100 percent coverage; direct inference: one testbench generation without feedback; Pass@1 estimated from five samples; models in instruct mode with their recommended sampling; higher is better. Source: arxiv.org. Saturation forecast: Around January 2027. 14 models tracked.
