Abstract

In this paper we present a new efficient algorithm for retiming sequential circuits with edge-triggered registers under both setup and hold constraints. Compared with the previous work [17], which computed the minimum clock period in O(|V|3|E|lg|V|) time, our algorithm solves the same problem in O(|V|2|E|) time. Experimental results validate the efficiency of our algorithm.
