Choosing appropriate logic gate structures based on path criticality. B. Post-Layout Optimization (ICC2) As of 2021, ICC2 provides advanced optimization features:
The Synopsys Timing Constraints and Optimization User Guide 2021 provides a detailed overview of the company's timing analysis and optimization capabilities. This guide is designed for digital designers, verification engineers, and design managers working with Synopsys' EDA tools. The guide covers the following topics:
These define the timing relationship between the design and the outside world. synopsys timing constraints and optimization user guide 2021
set_input_delay defines the amount of time taken by the external environment before the data arrives at the chip's input port, relative to a reference clock.
Once a design is physically implemented, a final, accurate timing analysis must be performed before tape-out. Choosing appropriate logic gate structures based on path
Virtual clocks exist only in the timing environment and do not map to a physical port or pin in the netlist. They serve as a reference point for bounding input and output delays.
