Details for Gate Delay Characterization
Estimating the delay of a gate is a crucial task in digital circuit design. Whereas it is relatively easy to measure characteristic gate delay values like worst-case rising and falling transition delays via simulations, the question of determining these values for all the gates in a circuit without individual measurements. After all, both the surroundings of a gate (like load capacitance and interconnect characteristics) and operating conditions (like supply voltage and input slewrate) have a severe impact on gate delays. Models like CCSM and ECSM used in static timing analysis do a very good job for determining worst-case delays, but cannot provide all characteristic delay values of interest. The goal of this assignment is to explore ways to accomplish this.
Description
Your task would be to contemplate ways to develop a model for determining other characteristic delay values of interest from existing delay models, library data, technology information etc., and to validate your model by means of analog SPICE simulations.
