Abstract

Provided is a system and method for designing the layout of integrated circuits or other semiconductor devices while directly accessing design rules and a library of design features by interfacing with a GUI upon which the design layout is displayed. The design rules may be directly linked to the design features of the pattern library and imported into the device layout. The design rules may be directly accessed while designing the layout or while conducting a design rule check and the design features from the pattern library may be used in creating the layout.

Claims
