Split and merge design flow concept for fast turnaround time

摘要

A method and system is disclosed to improve the turnaround time to provide adequate time to meet project schedules in the event that adjustments or modifications to the design are necessary. A method for improving a turnaround time for design verification of a process database representing a semiconductor design includes the steps of (a) deriving a timing database and a (DNE) database from the process database; (b) performing, using the timing database, one or more design changes and one or more timing verifications and corrections to generate a modified timing database; (c) initiating, using the process database, physical validation of the semiconductor design prior to completion of step (b) to generate a modified DNE database; (d) merging the modified timing database with the modified DNE database to form a modified process database; and (e) performing, using the modified process database, one or more design verification checks of the semiconductor design.
