    Default Cyclone V E Uniphy Controller Error 174077

    Hello All, I am working with a Cyclone V E development board and I'm having a problem creating the uniphy hard memory controller.
    I instantiated the uniphy hard memory controller in Qsys and the system completes synthesis but during fitting I get the following error.
    I cannot find any information on this error and I am at a loss as to how to resolve it.
    Any help is appreciated. Thanks!

    The assignments to the I/O pins for the memory are incorrect for your memory IP configuration. The memory IP should have generated a Tcl script that you can run to set all the assignments correctly (pin_assignments.tcl I believe it's called).

    Thank you, I did run the script. The error occurred after running the script.
    Any idea which assignments might be wrong?
