UltraScale+ Memory IP interfaces that are generated using a custom memory part will fail during opt_design if generation of the IP output products is skipped.

If generation of the IP output products is skipped, the following error message will occur:

ERROR: [Mig 66-99] Memory Core Error - [u_ddr3_0] MIG Instance port(s) c0_ddr3_addr[14],c0_ddr3_addr[15],c0_ddr3_ba[2],c0_ddr3_cas_n,c0_ddr3_we_n is/are not connected to top level instance of the design

Solution

This error message is not intuitive and does not explain the reason for the failure. This will be addressed in a future release of Vivado.

To work around the issue, please generate the IP Output Products using the Global or Out-Of-Context (OOC) options.
