When a Signal travels from its Start Point to its End Point the path traversed by the Signal is known as the Timing Path. To perform timing analysis the complete circuit is divided into different Timing Paths and then the delay is calculated. The Setup and Hold requirements of each Timing Path are calculated and optimized further. rmb players

WebTherefore, (T clk – t1) is the setup time or setup margin or setup window (S) for the data to arrive to the receiver. On the other hand, there’s a requirement from Sender (again, a flip-flop), that if data has to change after sending clk edge, that change should happen atleast after a finite time (say ‘t2’), after clock edge arrives.

WebApr 26, 2024 · When using flip-flops in digital VLSI designs, we must consider the following: Setup time: the input to a flip-flop should be stable for a certain amount of time (the setup time) before the clock transitions; otherwise, the flip-flop will behave in an unstable manner, referred to as metastability. Hold time: the input of a flip-flop should ...

In this article, we will discuss the timing window analysis of crosstalk and the prevention techniques of crosstalk.

WebDefinition of Hold time : Hold time is defined as the minimum amount of time after the clock's active edge during which data must be stable. Similar to setup time, each sequential element needs some time for data to remain stable after clock edge arrives to reliably capture data. This duration is known as hold time.
