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...
你可以把时钟信号表示为方波,此时它的 ON 和 OFF 时间长短等同。 The reciprocal of the time period of a clock signal is known as the frequency of the clock signal. All sequential circuits are operated with clock signal. So, the frequency at which the sequential circuits can be operated according...
Redesigning an integrated circuit and manufacturing the corrected design takes months and millions of dollars in today's advanced technologies, so hold time violations must be taken extremely seriously. Putting It All Together Sequential circuits have setup and hold time constraints that dictate the ...

Digital circuitry will usually contain multiple components which when combined together will create sequential circuits. By using the different delay parameters of thesequential logic components, you can calculate the maximum clock frequency at which your circuits will generate the best results. There ar...

In general, the specifications of sequential circuits are classified into (a) clock stoppable type and (b) clock unstoppable type. The circuits of type (b) are further generally classified into (b-1) circuits having feedback of the output of a memory element and (b-2) circuits not having...
For the example where the circuit 150 includes sequential logic (e.g., flip-flops), the glitches may cause setup time and/or hold time violations in the sequential logic. To prevent glitches during clock gating, the clock gating circuit 130 may be implemented with a glitch-free clock gating...
For the first time, we formulate the problem of allocating pulse widths, out of a small discrete number of predefined widths, and scheduling clock skews, within a predefined upper bound on skew, for optimizing pulsed latch-based sequential circuits. We then present an algorithm called PWCS_...
A clock circuit for the reading of sequential information elements includes a phase-locked loop for the control of the controlled oscillator. In the case of a reading system with n tracks, the phase computation circuit, the digital filter and the controlled oscillator each include as many ...
