WebA few examples of relevant metrics include: . Propagation time The time required for a signal or wave to travel from one point of a transmission medium to another. . … WebClock is propagated after placement because the exact location of cells and modules are needed for the clock propagation for the estimation of accurate delay, skew and insertion delay. Clock is propagated before routing of signals nets and clock is the only signal nets switches frequently which act as sources for dynamic power dissipation. tabletop buddha water fountain

Paths to this check are disabled because of case analysis or a logic constant propagated through the design (for example, caused by a signal tied high or low).

WebThe clock is propagated through the entire clock tree network in the netlist in order to determine the clock latency. In other words, the delay across each cell in the clock tree and the interconnect wiring delay between the cells is taken into account. The following command instructs PT to propagate the clock through the clock network: WebClock uncertainty is the time difference between the arrivals of clock signals at registers in one clock domain or between domains. Pre-layout and Post-layout Uncertainty Pre CTS …
