As a potential alternative to CMOS technology, QCA provides an interesting paradigm in both communication and computation. However, QCA's unique four-phase clocking scheme and timing constraints present serious timing issues for interconnection and feedback. In this work, a cut-set retiming design procedure is proposed to resolve these QCA timing issues. The proposed design procedure can accommodate QCA's unique characteristics by performing delay-transfer and time-scaling to reallocate the… CONTINUE READING
