Description

Introduction:

RedHawk-SC is an advanced power integrity and reliability analysis platform. It is used for static and dynamic IR drop, electromigration (EM), and noise analysis in modern SoC designs. Moreover, it supports multi-corner multi-mode (MCMM) analysis. Therefore, it ensures accurate power verification across different operating conditions, process variations, and functional modes for robust signoff.

In addition, it is widely used in advanced node designs (7nm and below). It helps manage increasing design complexity, large-scale power grids, and highly variable workloads. As a result, it enables early detection of voltage drops and reliability risks, improving design closure efficiency and reducing tapeout iterations.

Learner Prerequisites:

• Basic understanding of VLSI design flow and physical design concepts
• Familiarity with power integrity concepts such as IR drop and EM
• Knowledge of timing analysis, corners, and modes (STA basics)
• Exposure to UPF/CPF power intent concepts (recommended)
• Basic scripting and EDA tool usage experience (Tcl preferred)
