Abstract

Latches are extensively used in high-performance sequential circuit designs to achieve high frequencies because of their good performance and time borrowing feature. However, the amount of timing uncertainty due to crosstalk accumulated through latches could be larger than the benefit gained by time borrowing. In this paper, we show that the trade-off between a latch and a flop can be leveraged in a sequential circuit design with crosstalk, so that the clock period is minimized by selecting a configuration of mixed latches and flops. A circular time representation is proposed to make coupling detection easier and more efficient. Experiments on our heuristic algorithm for finding an optimal configuration of mixed latches and flops showed promising results.
