Nettet19. apr. 2015 · Setup times and hold times describe the limits relative to the active clock edge of a "window" within which the input data must be valid for the data to be reliably … NettetA hold constraint specifies how much time is necessary for data to be stable at the input of a sequential device after the clock edge that captures the data in the device. This constraint enforces a minimum delay on the data path relative to the clock edge. The following example shows how STA checks setup and hold constraints for a flip-flop:

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. Share. Cite. pear diamond eternity bandNettet5. aug. 2014 · 1. Setup time limits the fastest frequency (shortest period) for the clock.
