Setup and Hold Time Basics - EDN
Apr 19, 2012 · Hold time is defined as the minimum amount of time after the clock’s active edge during which data must be stable. Violation in this case may cause incorrect data to be latched, which is known as a hold violation. Note that setup and hold time is measured with respect to the active clock edge only.
