A complete set of analytical gate performance models is developed based on driving current analysis. Closed-form equations for gate delay and output slew are obtained, which capture the dependence on key process and design parameters, such as the input slew, threshold voltage, etc. Using these formulas, gate performance of various topologies is accurately predicted under both nominal and variational...
This paper introduces a novel compact implicit model for a probabilistic set of waveforms (PSoW) which arise as representations for uncertain signal waveforms in Statistical Static Timing Analysis (SSTA). In traditional SSTA tools, signals are just represented as (distributions of) arrival time and slew. In our approach, to increase accuracy, PSoW's are used instead. However, to represent PSoW's explicitly,...
