A design cannot be optimized in a vacuum. Synopsys requires precise data regarding the external environment to optimize the internal logic paths. Input and Output Delays Share public link A design cannot be optimized in a vacuum

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

The Synopsys Design Constraints (SDC) format is the industry-standard language used to communicate design intent. SDC files use a Tcl-based syntax to describe: Link environments and operating conditions Clock waveforms and characteristics Input and output delays Timing exceptions (false paths, multicycle paths) Design Environment Setup

Sets up input delays, output loads, and driving cells.
