The quasi-delay-insensitive (QDI) model assumes that all the forks are isochronic. The isochronic-fork assumption requires uniform wire delays and uniform switching thresholds of the gates associated with the forking branches. This paper presents a method for determining such forks that do not have to satisfy the isochronic fork requirements, and presents experimental results that show many isochronic forks assumed for existing QDI circuits do not actually have to be “isochronic” or can be even ignored
