Synopsys Timing Constraints And Optimization User Guide 2021 (2026)

If your slack is negative (VIOLATED), review this checklist based on the 2021 guide's guidelines:

Static Timing Analysis evaluates the delay of a digital circuit without simulating its actual functionality. It calculates the data propagation delay along all logical paths and compares it against the clock requirements. Timing Paths synopsys timing constraints and optimization user guide 2021

Defines false paths, multicycle paths, and case analysis. If your slack is negative (VIOLATED), review this

[ External Device ] ----> ( Input Port ) ----> [ Internal Register ] |--- Input Delay ---| Input Delay Constraints ( set_input_delay ) [ External Device ] ----> ( Input Port

[ RTL Code + SDC Constraints ] | v [ Translation & Elaboration ] | v [ Logic Optimization & Structuring ] <--- Cost Function Matrix | v [ Gate Mapping (Target Technology) ] | v [ Optimized Gate-Level Netlist ] The Cost Function Matrix
