Chapter Summary
The SDF file is used exhaustively throughout the ASIC world to perform dynamic timing simulations. The chapter briefly summarizes the contents of the SDF file that is related to ensuing discussions.
The chapter also discusses procedures for generating the SDF file from DC and PT, both for pre-layout and post-layout simulations. Along with command description, various helpful techniques are described to “massage” the SDF, in order for the simulation to succeed. These include fixing the clock latency and clock transition at the pre-layout level, and avoiding unknown propagation from selective logic of the design for successful simulation.
The final section gathered all the information and put it together in the form of DC scripts for pre and post-layout SDF generation.
