Flip flop setup time hold time
WebJun 27, 2024 · There are basically 3 types of factors which affect the working of a flip flop: 1. Setup Time: This is defined as minimum amount of time required for which an input should be stable just before the clock transition occurs. Suppose we have a positive edged JK flip-flop and setup time is t= 1ns seconds. http://ece-research.unm.edu/payman/classes/ECE321/lectures/lecture25.pdf

WebDec 8, 2024 · It will help solve any hold violations. 3. Increase the clock-q delay of launch flip-flop. Similar to the previous fix, by choosing a flop that has more clock-q delay, delay can be induced in data path logic. It will ease timing and help solve hold time violations. 4. Use a slower cell for launch flip-flop. WebDec 13, 2016 · If the delay that you add to the data is greater than the FF's actual hold time requirement, the overall hold time requirement for the combination can be negative. It might be important to point out that while either setup or hold can be positive or negative, the expression "setup + hold > 0" must always be true (relative to the clock edge your ...

WebThe 74LVC377 is an octal positive-edge triggered D-type flip-flop. The device features clock (CP) and data enable (E) inputs.When E is LOW, the outputs Qn will assume the state of their corresponding D inputs that meet the set-up and hold time requirements on the LOW-to-HIGH clock (CP) transition. Input E must be stable one set-up time prior to the …
