Synopsys Timing Constraints And Optimization User Guide 2021

Synopsys Timing Constraints and Optimization User Guide

The is a primary reference for engineers using tools like Design Compiler , Fusion Compiler , and PrimeTime to specify design intent and achieve timing closure . Core Focus Areas

• Ideal Mode: Used during RTL synthesis and logic optimization. The guide details how to accurately model clock uncertainty and latency using set_clock_latency -source versus simple network latency.
• Propagated Mode: Post-CTS (Clock Tree Synthesis) reality.

Optimization goal: Achieve a maximum delay of 10 ns between the input and output ports.

The 2021 guide outlines a structured four-step methodology for defining constraints to ensure reliable timing closure : synopsys timing constraints and optimization user guide 2021
