A process for redesign of a sequential circuit to provide a functionally equivalent circuit that can operate with a shorter clock cycle. It includes forming a path graph of the circuit, classifying short and long arcs of the graph and developing sets of short and long path inequalities from ...
A clock signal is a periodic square wave that indefinitely switches from 0 to 1 and from 1 to 0 at fixed intervals. Clock cycle time or clock period: the time interval between two consecutive rising or falling edges of the clock. Clock Frequency = 1 / clock cycle time (measured in cycle...
In this paper, we show that the trade-off between a latch and a flop can be leveraged in a sequential circuit design with crosstalk, so that the clock period is minimized by selecting a configuration of mixed latches and flops. A circular time representation is proposed to make coupling ...
Setup Time: Minimum time period during which data must be stable before the clock makes a valid transition. For example, for a posedge triggered flip-flop, with a setup time of 2 ns, Input Data (i.e. R and S in the case of RS flip-flop) should be stable for at least 2 ns befor...
The clock rate prior was set to 0.0006 sites/substitutions/year and the kappa prior set to 5.5 was applied. The reproductive number was set to 10 dimensions across the study period. Four independent runs of 300 million generations was run with a Bactrian operator schedule using BEAST 2, with...

we employed a birth-death skyline serial (BDSKY) model as implemented in BEAST 2. For each variant, an optimized relaxed clock model with the HKY85 nucleotide substitution model was used40. The clock rate prior was set to 0.0006 sites/substitutions/year and the kappa prior set to 5.5 was...
Based upon a target clock period, a determination is made of a change in delay in one or both of the first and second non-common clock tree paths that increases permissible variation of clock accuracy, consistent with the target clock period. Delay of one or both of the first and second ...
