Abstract
A method for estimating decoupling capacitance during an ASIC design flow is disclosed. The method includes precharacterizing a set of power grid structures to model their respective noise behaviors, and storing the respective noise behaviors as noise factors in a table. During the ASIC design flow for a current design that includes at least one of the precharacterized power grid structures, the corresponding noise factor from the table is used to calculate decoupling capacitance for the current design.
