Webb10 aug. 2011 · Any MMCM or PLL that you’ve used to generate a clock requires calibration after it is reset. Hence, you may have to insert additional logic in the global reset path to stabilize that clock. Tip 3: Ensure that the clock the MMCM or PLL has generated is stable and locked before deasserting the global reset to the FPGA. natural research people herbal collar
