SYSTEM FOR AND METHOD OF TUNING CLOCK NETWORKS CONSTRUCTED USING VARIABLE DRIVE-STRENGTH CLOCK INVERTERS WITH VARIABLE DRIVE-STRENGTH CLOCK DRIVERS BUILT OUT OF SMALLER SUBSET OF BASE CELLS

摘要

PROBLEM TO BE SOLVED: To reduce the cost and manufacturing time for fabricating a clock distribution network comprising variable drive-strength clock drivers.SOLUTION: A system for tuning an integrated circuit design comprises: a processor; a synthesis module configured to generate a collection of macrocells instantiated in the integrated circuit design, where the integrated circuit design has a plurality of drivers for driving capacitive loads on the integrated circuit; a place-and-route module configured to choose locations for input and output net lists of each of the macrocells, generate terminals marking the locations, and determine names of the terminals and pins for the macrocells; and a verification module configured to tune the integrated circuit by balancing a capacitive load on the plurality of drivers according to predetermined criteria.
