Description

Introduction

Synopsys RedHawk-SC is a scalable, signoff-grade power integrity analysis platform used in advanced semiconductor design. It supports accurate static and dynamic IR drop, electromigration (EM), and noise analysis for complex SoC designs. Therefore, it enables robust power delivery verification at advanced process nodes.

In addition, it is widely adopted in high-performance and low-power chip design flows to ensure silicon reliability. It helps reduce late-stage failures and meets strict signoff requirements across multi-corner, multi-mode environments. Moreover, it integrates seamlessly with physical design and signoff ecosystems. As a result, it provides fast analysis turnaround and highly accurate correlation with silicon results.
