Description
Introduction
Synopsys PrimeTime is an industry-standard Static Timing Analysis (STA) tool used for timing signoff in digital IC design. It analyzes timing across multiple modes and PVT corners. As a result, engineers can detect setup, hold, and asynchronous timing violations early. In addition, it helps improve design reliability before fabrication. Therefore, it is widely adopted in advanced VLSI flows.

- Familiarity with combinational and sequential circuits
- Knowledge of flip-flops, latches, and clocking schemes
- Understanding of timing concepts such as propagation delay and clock skew
- Exposure to Verilog netlists and basic STA flow is beneficial
