Abstract
An improved, systematic approach is provided for automatically determining which cells in a circuit should be replaced to satisfy timing adjustment requirements (TAR's), and automatically replacing the cells with replacement cells to meet the TAR's. With the improved approach, there is a high likelihood that an optimal replacement scheme will be found which requires the fewest number of cells to be replaced while still satisfying all of the TAR's.
