Deployment of transmission gate logic cells in application specific integrated circuits

摘要

A method is provided for designing an integrated circuit. The method includes generating a net list of an integrated circuit design, wherein the net list includes one or more component cells selected from a cell library. The component cells include transmission gate logic cells and sourcing cells that drive the transmission gate logic cells. Each transmission gate logic cell has an associated timing model with a timing characteristic defined as a function of a driving strength attribute of a sourcing cell used to characterize the transmission gate logic cell. The method further includes auditing the net list to determine if a given sourcing cell in the integrated circuit design has a sufficient driving strength based at least on the driving strength attribute of a transmission gate logic cell being driven by the given sourcing cell.
