Abstract :
Quasi-Delay insensitive (QDI) circuits are the most robust and practical circuits that can be built and are resilient to process, temperature and voltage variations. This paper proposes a novel energy and cost efficient synthesis scheme to translate any Boolean functions into 4-phase handshaking QDI circuits with hybrid dual-rail (DR) and 1-of-4 (OOF) encoding signals. Preliminary experimental results in FPGAs indicate significant cost and energy reduction over DR DIMS design.
