Synopsys Timing Constraints And Optimization User Guide 2021 Guide

: Automatically adding buffers to long wires to reduce interconnect delay and fix high fan-out nets.

The user guide outlines several stages of optimization to meet Performance, Power, and Area (PPA) goals. synopsys timing constraints and optimization user guide 2021

: Start with "loose" constraints to explore the design space, then tighten them as the physical floorplan matures. : Automatically adding buffers to long wires to

: The primary constraint is create_clock , which defines the period and duty cycle. Secondary clocks, such as generated clocks for frequency dividers, are defined using create_generated_clock . synopsys timing constraints and optimization user guide 2021

: Leveraging clock gating and multi-threshold CMOS (MTCMOS) cells to reduce both dynamic and leakage power during the timing-closure process. 4. Advanced Features in the 2021 Release
