MIG UltraScale - When using the Auto Assign feature of Bank Planner, an error message is not issued when the memory ports do not fit into a half bank


Version Found: v7.0
Version Resolved: See (Xilinx Answer 58435)

I am using the Auto Assign Controllers option in the Bank Planner.

If a half bank with 2 bytes is selected for a controller, not all ports of the controller are placed and no error message is generated.

An error message similar to the following should be generated:

[u_my_mig] Could not auto place in the given bank(s): . At least 1 banks are required for auto placement with sufficient number of unassigned pins.


This issue will be resolved in a future release.

Until this time, you must manually assign the bytes within the banks and not use Auto Assign Controllers.
