: Defining the maximum allowable rise/fall time for signals. 6. Optimization Techniques Optimization Phases
Essential for clock dividers or PLL outputs. It ensures the tool understands the phase relationship between the master clock and its derivatives. synopsys timing constraints and optimization user guide 2021
Buried in Chapter 6 ("Optimizing for High Speed") is a warning that saves countless ECO cycles: : Defining the maximum allowable rise/fall time for signals
Reorganizing logic gates to reduce the levels of logic in a critical path. It ensures the tool understands the phase relationship
Whether you are using Design Compiler (DC) for synthesis or IC Compiler II (ICC2) for place-and-route, understanding how to communicate your timing intent is the difference between a successful tape-out and a failed chip. 1. The Core Philosophy: SDC (Synopsys Design Constraints)
Based on standard Synopsys documentation frameworks, the content is typically organized into the following functional sections:
