Webclock buffers distributed very nonuniformly over the chip. E. Jitter Undesired variations in the cycle period are called jitter. Jitter reduces performance because some cycles are short, and the chip frequency must be slowed to avoid long-path errors. Gen-erally, a phase-locked loop (PLL) is used to generate a low-jitter WebThe multiple clock trees attached to the coarse mesh gives the technology its name. As mentioned, designers may target the OCV performance level by targeting the depth of the clock tree. In clock mesh, the guideline is to restrict the buffer and clock-gating depth to one or, at most, two levels. photographers virginiaWebInput Clock Frequency: (MHz ) ... you will see a message stating this.
