Flip-Flop Timing Constraints and Time Borrowing in Digital Sequential Circuits
In digital sequential circuits within Computer Engineering, flip-flops and latches establish data stability constraints governed by setup time ($t_{setup}$), hold time ($t_{hold}$), propagation delay ($t_{pd}$), clock-to-Q latency ($t_{CQ}$), and skew. Flip-flop systems operate strictly on edge-triggered intervals where maximum logic delay is bounded by the sum of timing parameters within a single clock cycle, whereas latch-based two-phase non-overlapping clocks introduce "time borrowing" mechanisms that relax constraints during active high levels but nullify tolerance for negative-clock-skew in Maximum Delay calculations.
