Data check setup time
WebDec 9, 2024 · In this article, we will discuss the methods that are used in back-end flow to solve setup and hold time violations. In basic data path logic, the data from the launch flop is sampled by capture flop in the next clock edge. Hence, the setup time check occurs in the next active clock edge while the hold time check occurs in the same clock edge. WebSetup time: The time the input D must be stable before the clock C is triggered (pos edge or neg edge) is defined as setup time. If the data is not stable at least setup time before the clock edge, output will be undetermined. Hold time: The time the input D must be stable after the clock C is triggered (pos edge or neg edge).

Web12.1. Setup Time Setup Time is the amount of time the synchronous input (D) must show up, and be stable before the capturing edge of clock. This is so that the data can be stored successfully in the storage device. Setup violations can be fixed by either slowing down the clock (increase the period) or by decreasing the delay of the data path logic. WebAug 30, 2024 · Timing analysis of data setup time.
