Bridging the Last Mile of Circuit Design: PostEDA-Bench, a Hierarchical Benchmark for PPA Convergence and DRC Fixing

Caiwen Ding, Jinwei Tang, Nuo Xu, Pengju Liu, Yu Cao

LLM agents succeed on simple post-EDA tasks but reach only 37% and 20% success on practical DRC reasoning and multi-objective PPA.

Claims

C1strongest claim

Across eight commercial and open-source LLMs under multiple agent scaffolds, we find that agents handle synthetic DRC-Essential and single-objective PPA-Mono reasonably well but degrade sharply on the more practical DRC-Reasoning, where the best success rate is 36.66%, and PPA-Multi, where the best success rate is 20.00%; vision augmentation consistently enhances DRC-Bench; and trade-off reasoning, rather than knob knowledge, is the dominant PPA-Multi bottleneck.

C2weakest assumption

The 145 tasks across the four categories in PostEDA-Bench, supported by EDA toolchains with machine-checkable evaluation, are representative of real-world post-EDA challenges and provide a fair test of agent capabilities.

C3one line summary

PostEDA-Bench shows LLM agents succeed reasonably on basic DRC and single-objective PPA tasks but struggle on practical DRC reasoning (best 36.66% success) and multi-objective PPA (best 20% success).
