WebJan 4, 2011 · when i synthesis & fit my design, hold time violation is reported at my output port in fast model timing analysis. the fpga was connected with some slow device, which requires a relative large hold time, as 10ns. it is always compiled with negative slack, about -3~-7ns. i think i can add some del... WebMar 16, 2024 · An FPGA logic unit has a form like this: When you de-assert the reset signal the input to the flip-flop changes from the reset value to the next value. If the clock edge occurs sooner than the setup time requirement, you will get a timing violation. Similarly you can get a hold time violation, if the de-assert occurs just after the clock edge. 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 … talbot road police station
