WebCase 1: Launch Flop at Slow Clock and Capture Flop at Faster Clock Suppose Clock of Capture Flop is three times faster than Clock of Launch Flop. It means Capture Flop will receive Data once in the duration of three Clock Cycles. It will lead to unnecessary wastage of Clock Cycles and Power Dissipation also. Web23 nov. 2024 · 当做 时序分析 时launch clock path与capture clock path存在共同的一段路径(common path),若使用ocv分析模式,会导致共同路径上的cell产生不同的delay值,为了消除这种悲观的情况,eda工具引入crpr (clock reconvergence pessimism removal),也叫cppr (clock path pessimism removal),以此抹平公共路径上的差异。 ICC2中使用如下命 …

So for example, a section of the clock tree might have a delay of 1ns-1.2ns. During setup analysis the larger delay will be used for the launch clock and the slower delay for the latch clock. Common Clock Path Pessimism removal will remove this from any common portions of the clock tree since it ...
WebFor the capture IDDR, the edge starts at the primary clock, propagates through the PLL (which adjusts it for clock propagation but not for the phase shift), and ultimately to the … Web23 feb. 2024 · The launch clock path and the capture clock path share a portion of the clock tree (B1, B2) and then diverge from the common point. This common path delays are multiplied with different derates (early and late), resulting in different delays. These cells have max delay in launch path and min delay in capture path.
WebCPPR: 在考虑OCV 的STA 分析中,会分别对launch clock path 跟capture clock path 设不同的derate 值,如setup check: launch clock path 会设一个late 的derate, capture …
WebUsing the one-hot launch-on-shift approach, a launch clock pulse followed by a capture clock pulse are applied to only one clock domain during each capture window, while all other test clocks are held inactive. An example timing diagram is shown in Fig. 2.
