Clock_dedicated_route backbone

WebAug 20, 2024 · Sub-optimal placement for a clock-capable IO pin and PLL pair. If this sub optimal condition is acceptable for this design, you may use the CLOCK_DEDICATED_ROUTE constraint in the .xdc file to demote this message to a WARNING. However, the use of this override is highly discouraged. WebWith clock networks, it's always best to assign fixed locations to the dedicated components to make sure your results are repeatable and to understand the topology as it affects QOR, or in your case the ability to place & route at all. Regards, EAI-Design.com - Digital Design Golden Rule: If its not tested - its broken.

WebResolution: A dedicated routing path between the two can be used if: (a) The clock-capable IO (CCIO) is placed on a CCIO capable site (b) The MMCM is placed in the same clock region as the CCIO pin. If the IOB is driving multiple MMCMs, all MMCMs must be placed in the same clock region, one clock region above or one clock region below the IOB. survivor s1 e1
