abstract
Logic rewriting is a critical and time-consuming task in logic synthesis, which determines the area and delay of the synthesized circuit. However, existing parallel solutions for this task suffer from limitations in terms of runtime or quality in large-scale complex circuits. In this paper, we propose a divide-and-conquer parallel approach namely DACPara for high-quality logic rewriting in large-scale circuits. Specifically, after nodes in AIG are divided in each level, dynamic global information is considered to divide and conquer rewriting into three stages for parallel processing. Experiments show that DACPara using 40 CPU physical cores can be 34.36x and 1.96x faster than logic rewriting in ABC and the state-of-the-art CPU parallel method on large benchmarks, respectively, with extremely comparable quality of result. Also, for large-scale complex benchmarks, compared with state-of-the-art GPU accelerated method ours can achieve 1.1% quality improvement.
