Abstract

An improved method and system are disclosed for utilizing abstracted versions of layout portions in conjunction with parameterized cells (pcells). One significant advantage is that abstracted versions of pcells can be generated from normal pcells and stored in a pcell cache, which avoids the need to abstract layout pcells on the fly.
