I am receiving the following Critical Warning for my Vivado 2014.4 IPI design that includes a custom IP:
This occurs when a Custom IP is connected to another IP.
However the ports from the warning message are not needed, and as a result are not used.
The warning message states that the Ports do not have a tie off value specified.
To specify this value, you can do the following:
Open the Custom IP in IP Packager, by right clicking the IP in IP Catalog > Edit.
