Classification: G06F

Abstract:
A method for facilitating designing an integrated circuit, comprising the steps of:propagating process parameter data from a process simulator to obtain normalized distributions of electrical properties of the process parameter data relating to manufacturing an integrated circuit;dividing up the integrated circuit into at least one simple standard cell and at least one complex cell;modeling the at least one simple standard cell as a circuit, and using the propagated process parameter data to determine at least one attribute of the at least one simple standard cell;using the propagated process parameter data to determine a drain-to-source current and drain-to-source voltage relationship for the at least one complex cell; anddetermining at least one worst case design parameter for the integrated circuit using the at least one attribute of the simple standard cell and the at least one drain-to-source current and drain-to-source voltage relationship of the at least one complex cell.
