D Flip Flop (D Latch): What is it? (Truth Table & Timing …

WebIt is the property of latch, a path ending at a latch can borrow time from the next path in the pipeline such that the overall time of two paths remains the same. STA 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 ... WebApr 19, 2012 · Hold time is defined as the minimum amount of time after the clock’s active edge during which data must be stable.
