Synopsys Timing Constraints And Optimization User Guide 2021

By default, static timing engines assume that data must travel from a launching flip-flop to a capturing flip-flop within . However, real-world digital architectures often contain functional paths that deviate from this rule. Over-constraining these paths causes unnecessary congestion and area bloat. False Paths

The content in this article is based on notes and summaries from that version. It is important for engineers to always refer to the latest official documentation for their specific tool version, as features and commands are continuously updated. Later versions, like the release used in some community resources, may include changes that supersede the 2021 guide. synopsys timing constraints and optimization user guide 2021

Restricts the maximum time allowed for a signal edge to transition from low to high or high to low. Slow transitions cause massive internal dynamic power dissipation and unpredictable delays. By default, static timing engines assume that data

An ASIC or FPGA design is divided into four distinct categories of timing paths:
