Abstract

A parameterized cell library including variable names corresponding to characteristics of components on an integrated circuit design may reference variable values stored in a first rule layer via internally used rule names stored in a second rule layer. The first and second rule layers may be stored as association tables. The first rule layer may store rule names corresponding to one or more geometric constraints of the integrated circuit design, and the rule names may directly reference variable values derived from a technology manual. The second rule layer may store internally used rule names corresponding to rule names stored in the first rule layer, and the internally used rule names may reference the rule names stored in the first rule layer.
