Synthesis and Optimization Methodologies 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. Synthesis and Optimization Methodologies The primary goal of
Replaces the generic logic primitives with concrete, highly characterized standard cells from the technology foundry's Target Library ( .db files). Managing Design Rule Constraints (DRC) Artificially tight targets cause tool congestion
