The document explains setup time and hold time, which are critical for proper flip-flop operation; both require stable input values during their respective durations. A setup time violation occurs when inputs fluctuate before the clock event, while a hold time violation happens when inputs fluctuate after the clock event. It emphasizes the importance of maintaining constant input values to avoid these violations.
Setup and hold time violation in flip-flops
- 1. Setup Time & Hold Time Violation JONGHWAN Shin Ajou University
- 2. Setup time and Hold time • For proper operation of a flip-flop, flip-flop input need to be constant during setup time and hold time. • Setup time is the minimum amount of time to prepare an input before a clock event. • Hold time is the minimum amount of time to determine a value of an input after a clock event.
- 3. 1. Normal Operation The value of a input is constant during setup time and hold time. 201220874 신종환 201020103 여영근 201020124 이기안
- 4. 2. Setup time violation Flip-flop inputs are floating in setup time. Setup time violation is occurred. 201220874 신종환 201020103 여영근 201020124 이기안
- 5. 3. Hold time violation Flip-flop inputs are floating in hold time. Hold time violation is occurred. 201220874 신종환 201020103 여영근 201020124 이기안
