Abstract
The present invention relates to a system and method for adaptively adjusting delays along selected signal paths in order to equalize the signal delays at various distributed points within an integrated circuit. Where a signal traverses an initial outgoing path and a return path, delay elements disposed in each of the paths may be adjusted in order to set the entirety of the delay of the signal having traveled the entire signal trajectory equal to the delay present in a deliberately introduced delay element of known value. Alternatively, the inventive mechanism may control a selected one of two (or other plurality of) delay elements so as to automatically and adaptively adjust the delay value of the selected delay element so as to equalize the signal delay incurred along two or more signal paths.
