Synopsys Timing Constraints And Optimization User Guide 2021 < 2026 >

A false path is a path that exists topologically in the netlist but cannot execute logically, or a path that does not need to be timed (e.g., static configuration registers).

Used for asynchronous resets or synchronizer chains where timing analysis is irrelevant. synopsys timing constraints and optimization user guide 2021

The primary goal of providing accurate constraints is to enable the tools to optimize the design. The user guide details how synthesis and physical design engines use constraints to drive their optimization algorithms. A false path is a path that exists

The 2021 release of the user guide sits at a sweet spot. It bridges the gap between the traditional PrimeTime/ICC2 flows and the modern complexities of multi-corner, multi-mode (MCMM) design. multi-mode (MCMM) design.
