Abstract
A method for cell characterization with Miller capacitance includes characterizing input capacitance of an input of a first stage in a cell by considering a first current transition at the input of the first stage up to a first stop time. The first stop time occurs during the first current transition exhibits a substantial tail portion contributed by the later of a first input voltage transition and a first output voltage transition reaching a corresponding steady state voltage. The first input voltage transition is associated with the input of the first stage. The first output voltage transition is associated with an output of the first stage coupled to the input through a capacitor.
