Abstract
Parasitic extraction is a useful tool for analyzing and improving timing and other characteristics of semiconductor chips. Parasitic resistance and capacitance values are determined and stored in arrays. The parasitic values are extracted for multiple corners with a single analysis of the layout. Multi-corner analysis is performed using the parasitic values thereby optimizing the timing across various temperature and process operating points.
