When I look at my timing report, the DCM Jitter calculations correctly use my System Jitter. However, when I look at my PLLs, the PLL Jitter is less than the System Jitter.
Is this possible, or is there a problem with my timing report?
By design, the PLLs can reduce jitter. This reduction in jitter is reflected in timing reports. Therefore, it is possible to see PLL Jitter at values lower than System Jitter.
