"WebAug 7, 2013 · In the picture above, the delay to clock sinks are given. The skew in this case is the difference between the maximum delay and minimum delay. `Skew = 20ns-5ns = 15ns` The goal of clock tree synthesis is to get the skew in the design to be close to zero. i.e. every clock sink should get the clock at the same time.

Figure 17 shows the histogram of the clock skew for each clock network. Single-mesh network and clock tree show the smallest and the largest clock skew variations, respectively.

WebOct 17, 2024 · You can use reference clock synchronization within the sample clock timed group and over sample clock timed group. As you can see, there is still some skew between each of the two groups due to the time it takes for the trigger signal to propagate across the backplane as well as the time required for the receiving device to … WebIn general, not all-skew parameters are of interest, but their discussion is included for illustration. The goal is to minimize skew to an acceptable value. The rule of thumb is that clock skew should be < one-tenth of the system clock period. For example, a system operating at 100 MHz has a period of 10 ns, and the clock skew should be <1 ns.

WebThe launch clock latency is 0ns and the capture clock latency is 2.5ns.
