WebHold time is the time for which data should be stable after the triggering edge of the clock to get latched properly by the flop. When a flop has a negative hold time the data can change even before the triggering edge of the clock and get latched properly. WebJun 7, 2013 · In a digital circuit, the hold time is the minimum time that an input signal must remain stable after the active edge of the clock in order to assure that that input is correctly recognized. If a circuit has a negative hold time, this means that the input can change before the clock edge and nevertheless the old level will be correctly recognized.
