Clock gating saves power but kills timing if done wrong. The 2021 guide dedicates an entire chapter to .
: Setting input and output delays ( set_input_delay , set_output_delay ) to model the external environment around the chip. synopsys timing constraints and optimization user guide 2021
The clock is the heartbeat of your SoC. The guide details three critical steps for clock definition: Clock gating saves power but kills timing if done wrong
Here are some best practices for timing optimization: The clock is the heartbeat of your SoC
The is a primary reference for digital designers using tools like Design Compiler and PrimeTime to achieve timing closure . The guide covers the creation and management of Synopsys Design Constraints (SDC) , which are essential for guiding synthesis and place-and-route tools to meet performance, area, and power goals. Core Timing Constraints
Whether you are using Design Compiler (DC) for synthesis or IC Compiler II (ICC2) for place-and-route, understanding how to communicate your timing intent is the difference between a successful tape-out and a failed chip. 1. The Core Philosophy: SDC (Synopsys Design Constraints)
