Synopsys Timing Constraints And Optimization User Guide 2021 2021 Page

When the design moves to physical implementation and signoff with , the timing constraints continue to guide the process. Engineers use PrimeTime, Synopsys' golden signoff-quality STA tool, to run the final, accurate timing checks before tapeout. It reads the design, parasitic information (like SPEF files), and the SDC constraints to ensure every timing path meets its requirements.

Once constraints are loaded, Synopsys Design Compiler (DC) and IC Compiler II (ICC2) utilize sophisticated optimization engines. A. Architectural Optimization (Pre-Layout) synopsys timing constraints and optimization user guide 2021

What are your and technology node (e.g., 7nm, 28nm)? When the design moves to physical implementation and

Not every path in a chip needs to meet a single-cycle timing requirement. The 2021 guide highlights how to properly use exceptions to prevent the tool from "fixing" paths that aren't broken: Once constraints are loaded, Synopsys Design Compiler (DC)

These define how long external logic takes to deliver data to the chip ( Tincap T sub i n end-sub ) or accept data from it ( Toutcap T sub o u t end-sub

Synopsys Design Compiler employs sophisticated algorithms to transform RTL code into an optimized gate-level netlist based on your constraints. Synthesis Optimization Phases
