Abstract: Portions of an electrical circuit described as a technology-independent network are automatically mapped by a computer to cells of a library to be used in manufacturing the circuit, using a common set of input signal names for both (the circuit and the cells). A computer readable medium stores models of cells of a library that were constructed using common input names, and also an association between each model and a cell that was used to create the model. In one embodiment, constructing models of the library cells includes reading first data from memory, wherein the first data corresponds to a first cell of the library of cells. The first data includes names representing input signals to the first cell. Thereafter, each name of the first data is replaced with a new name, respectively, thereby creating a first renamed data. A model of the first cell is generated from the first renamed data.
