How to measure setup and hold time
Web25 apr. 2002 · For finding my DFF setup time, I used the following script: .Param DelayTime = Opt1 ( 0.0n, 0.0n, 6.0n ) .Measure Tran MaxVout Max v (Q) Goal = 'v (Vdd)' .Tran 1n 20n Sweep Optimize=Opt1 Result=MaxVout Model=OptMod The waveform shows that the data signal falls before the clock rising edge (which I think is violating the hold time constraint). Web27 sep. 2014 · Timing analysis of a logic system depends on having well bounded delays from the clock pin to the output (Q, Qb) pins of the latches and flops. In order to bound the upper limit on the clock to Q delay time, we also have to bound the setup and hold time for data being stable relative to the clock.

Web15 nov. 2024 · The MAX5891 600Msps, 16-bit DAC provides an excellent case study example for this midpoint condition. The setup time is specified for -1.5ns, and the hold time is 2.6ns. Figure 2 illustrates the minimum setup time for the MAX5891. Note that, in reality, the data transition occurs after the capture clock has transitioned. WebLatch Setup and hold checks are the most common types of timing checks used in timing verification. Synchronous inputs have Setup, Hold time specification with respect to the …
