    Description

    This error can occur when simulating Cyclone® V, Arria® V, and Stratix® V transceiver designs if the "altera_mf" library is placed before the "altera_mf_ver" library in your script when re-executing the vsim command to start the simulation.

    Resolution

    To fix this issue the "altera_mf_ver" library must be called before the "altera_mf" library.

    For example

    vsim -t ps -novopt -L altera_mf_ver -L altera_mf
