Abstract
Embodiments of a computer system, a method, an integrated circuit and a computer-program product (i.e., software) for use with the computer system are described. These devices and techniques may be used to analyze an electrical characteristic of a logic gate electrically coupled to an output network in a stage. In particular, during the analysis, the effective capacitance of an output network coupled to a logic gate is approximated as a function of a total resistance of the output network, a total capacitance of the output network, and a geometric parameter of the output network. Using the effective capacitance and other parameters, such as a slew rate of an electrical signal applied to an input of the logic gate, an electrical characteristic of the logic gate, such as an input capacitance, is determined.
