ABSTRACT:
An enhanced library accessible by an EDA tool can include a base curve database and a plurality of curve data sets. Each curve data set refers to a standard cell having certain timing characteristics. To determine those timing characteristics, each curve data set identifies at least one base curve (in the base curve database) as well as a starting current, a peak current, a peak voltage, and a peak time. In one embodiment, each base curve can be normalized. The base curve(s), the starting current, peak current, peak voltage, and peak time can accurately model the functioning of the IC device, e.g. represented by an I(V) curve.
