Improved modelling and characterization system for logic simulation

An accurate input ramp-dependent timing model and practical characterization system is described. Compared to current implementations, the system drastically reduces the number of circuit simulations required for cell library characterization. Errors of the model predictions for delay chains are typically less than 2%.<<ETX>>
