WebAug 24, 2015 · The setup time is how long the input data needs to be held fixed before the clock, and hold time is how long it needs to remain fixed after the clock. If either of these specs is violated, then the answer is you don't know what state the output will settle at. Some flipflops have either a 0 setup time or 0 hold time. WebTo avoid hold time violations, require hold time ≤ (min FF prop. delay) + (min comb. circuit delay) – (max clock skew) CAD tools can check all FF-to-FF paths to verify In FGPAs, it …

How to modify D-FF Setup/Hold Times using Verilog?

WebWhen the propagation delay increases by a threshold (usually 1% or a few percent) from its value when the clock and data are not in close proximity, the time is classified as a "setup" or "hold" time. I've illustrated an … WebDefinition of Hold time : Hold time is defined as the minimum amount of time after the clock's active edge during which data must be stable. Similar to setup time, each sequential element needs some time for data to remain stable after clock edge arrives to reliably capture data. This duration is known as hold time.

WebSTA applies a concept of time borrowing for latch based designs. Whatever data launched from Flip Flop1 at ons it should be reached to Flip Flop2 at next active edge i.e. 10ns (ideal case when setup hold time and skew and clock delay all are zero). If data reaches at Flip Flop2 after 10ns will not be able to capture the correct data. WebClick and hold your mouse button on the page to select the area you wish to save or print.
