MHRC-Bench (Full Context) - HLS: leaderboard

Repository-level hardware code completion (MHRC-Bench, Zou et al., National University of Singapore, 2026) in high-level-synthesis C/C++: from a 2,048-token prompt holding the code before and after the target (fill in the middle) in a held-out repository, the model writes the missing syntactically complete code unit of one or more lines, without retrieval. Exact match in percent after comments and whitespace are stripped; higher is better.

Metric: Exact match (%; repository-level completion of syntactically complete high-level-synthesis C/C++ code units given the preceding and following code in a 2,048-token prompt, no retrieval). Source: arxiv.org. Saturation forecast: Around August 2027. 4 models tracked.
