Introduction

PrimeTime is a static timing analysis (STA) tool used in digital IC design. It verifies timing across different operating conditions. In addition, it helps engineers analyze performance variations in complex chip designs. Multi-Corner Multi-Mode (MCMM) analysis in PrimeTime evaluates timing across multiple process, voltage, temperature, and functional conditions. This training explains MCMM concepts and practical analysis techniques for robust chip design.
