Timing Optimization by Replacing Flip-Flops to Latches

简介atch circuits have advantage for timing and are widely used fur high-speed custom circuits. However, ASIC design flows are h don the circuits with flip-flops. Then, ASIC designers don't use latches. This paper describes a new timing optimization algorithm for ASIC by replacing flip-flops to latches without changing the functionality of the circuits. After latch replacement, mstricted retiming called fixed-phase retiming is carried out for timing optimization by minimizing the impact of clock skew and jitter. The experimental results show that 17% delay improvement of the benchmark circuits is achieved by proposed algorithms.
