Power reduction plays a vital role in VLSI design. Multi-bit flip-flop is an efficient method for clock power reduction. This method is to eliminate the redundant inverters by merging some flip-flops into multi-bit flip-flops. This multi-bit flip-flops can share the drive strength, dynamic power, area of the inverter chain and can even save the clock network power and facilitate the skew contro...

In this paper, a novel mixed selection methodology using flip-flops for scan and reset design is proposed. The method runs test generation for a sequential circuit to obtain reachable states of flip-flops and required states for hard-to-detect faults. The circuit is also explored so as to acquire the structural connection relationship among the flip-flops. By analyzing these three sets of infor...

Flip-flops are essential elements of a design from both delay and energy aspects. A significant fraction of the total power in highly synchronous systems 1s dissipated over clock networks. Hence, lowpower clocking schemes are promising approaches for future desfgns. Recently, there has been published several energy recovery flip-flops that enable energy recovery from the clock network, resultin...

There is a wide selection of flip-flops in the literature. Many contemporary microprocessors selectively use master-slave and pulsed-triggered flip-flops. Transmission gated flip-flop, are made up of two stages, one master and one slave Alternatively, pulse-triggered flip-flops reduce the two stages into one stage and are characterized by the soft edge property. The concepts discussed in the re...
