WebHold time is similar to setup time, but it deals with events after a clock edge occurs. Hold time is the minimum amount of time required for the input to a Flip-Flop to be stable after … WebSep 20, 2013 · 09-20-2013 03:41 PM. The timing violation dialog is telling you that your logic needs 10.64 ns to operate. If you invert that, you get a clock route of approximately 90 MHz. So you can change your clock rate to that or you can try rewriting your code to require less time. Since a large portion of your time is in routing logic, you might want to ... WebPlace-and-routed delays are extracted from place and routed design. Static timing analysis does not involve driving inputs input the system and analyzing resulting waveforms.

WebOct 28, 2024 · I need to monitor a signal as it is going into the FPGA, tracking down a potential noisy input or slow rising signal issue. I want to use an external oscilloscope to see what the FPGA sees (as opposed to the internal chip scope), so I thought I could just do this : However, this creates a timing violation that I don't understand. WebHold time violation is a violation of the hold time requirement. If the datasheet says the minimum required hold time is 10 ns and you change the data 5 ns after the clock edge, then you have committed a hold time violation and there is no guarantee which data value will end up on the flipflop output.
