Incremental timing-driven placement (TDP) is one of the most crucial steps for timing closure in a physical design. The need for high-performance incremental TDP continues to grow, but prior studies have focused on optimizing only setup timing slacks, which can be easily stuck in local optima. In this paper, we present a useful skew methodology based on a maximum mean weight cycle (MMWC) approach...
Skew optimization is an important stage of the physical design. Previous studies suggested various skew optimization algorithms [1–7]. However, many of them have only focused on the zero-skew optimization [1–3], and several recent studies focus on a useful-skew optimization [5–7]. In this paper, we propose a novel skew optimization method for useful-skew implementation. Our proposed method generates...
