** Error: Unresolved defparam somewhere** - ** Error: Unresolved defparam somewhere** 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 Custom Fields values: ['novalue'] Troubleshooting 1506805108 False ['Simulation'] ['FPGA Dev Tools Quartus II Software'] novalue 13.0 ['Arria® V GT FPGA', 'Arria® V GX FPGA', 'Arria® V GZ FPGA', 'Arria® V ST FPGA', 'Arria® V SX FPGA', 'Cyclone® V GT FPGA', 'Cyclone® V GX FPGA', 'Cyclone® V SE FPGA', 'Cyclone® V ST FPGA', 'Cyclone® V SX FPGA', 'Stratix® V GS FPGA', 'Stratix® V GT FPGA', 'Stratix® V GX FPGA'] ['novalue'] ['novalue'] ['novalue']
