Why do I see transceiver functionality problems when a transceiver reconfiguration controller is connected? - Why do I see transceiver functionality problems when a transceiver reconfiguration controller is connected? Description Due to a bug in the Quartus® II software version 13.0 and earlier, you may see transceiver functionality problems on Stratix® V, Arria® V, or Cyclone® V transceiver devices. The transceiver reconfiguration controller can have an incorrect initial state which may cause transceiver functional problems. The transceiver can be recovered by resetting the transceiver without a power cycle. Resolution To ensure the correct initial state of the reconfiguration controller, you can add QSF assignments below. set_instance_assignment -name POWER_UP_LEVEL HIGH -to *pif_interface_sel set_instance_assignment -name POWER_UP_LEVEL HIGH -to *pif_ser_shift_load Custom Fields values: ['novalue'] Troubleshooting 123597 False ['novalue'] ['novalue'] novalue novalue ['Arria® V FPGAs and SoCs', 'Cyclone® V FPGAs and SoCs', 'Stratix® V FPGAs'] ['novalue'] ['novalue'] ['novalue']
