ChipScope Pro - Inserting ChipScope cores in the PlanAhead tool generates unconnected ports
Description
Inserting ChipScope cores in the PlanAhead tool generates unconnected ports in the 13.3 and 13.4 design tools. BitGen displays DRC errors similar to the following when this occurs:
"ERROR:PhysDesignRules:10 - The network <xxxx_cs_ila_0_0> is completely unrouted."
Solution
To avoid this issue, add KEEP attributes to the nets reported in the BitGen DRC, and run again through XST and implementation.
