WebSTA applies a concept of time borrowing for latch based designs. Whatever data launched from Flip Flop1 at ons it should be reached to Flip Flop2 at next active edge i.e. 10ns (ideal case when setup hold time and skew and clock delay all are zero). If data reaches at Flip Flop2 after 10ns will not be able to capture the correct data. 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.
