RLC RULE GENERATION METHOD, RLC RULE GENERATION PROGRAM, LAYOUT DESIGNING METHOD, AND LAYOUT DESIGNING PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an RLC rule extraction method and layout designing method for selecting a different production tolerance condition according to the relation between driver resistance and wiring resistance. SOLUTION: The RLC rule generation method comprises steps of determining a plurality of RLC values including the resistance, inductor and capacity of wiring for a plurality of conditions related to the wiring, which are varied depending on the production variations; determining, from the plurality of RLC values, a minimum condition RLC value having the minimum delay time when the wiring resistance is larger than the driver resistance and a maximum condition RLC value having the maximum delay time; and determining a second maximum condition RLC value having the minimum delay time when the wiring resistance is smaller than the driver resistance and a second maximum condition RLC value having the maximum delay time.
