Abstract
A method for creating a physical layout of an analog integrated circuit characterized by the steps of developing a library of device modules and then assembling the device modules in an iterative fashion to create the desired analog circuit. The iterative process is preferably performed in a computerized spreadsheet program by developing an initial tiling script for the device modules, calculating the operating specifications of the circuit produced by the tiling script, comparing the calculated operating specifications against the desired operating parameters of the circuit and modifying the tiling script and repeating the process until the calculated operating specifications meet the desired operating parameters. In one embodiment the desired operating parameters include operating parameters of the analog circuit taken as a whole and in another embodiment the desired operating parameters include operating parameters of individual devices within the analog circuit. The device modules may be combined in a variety of fashions to make transistors and other devices of various operating specifications.
