The Quartus II Fitter Reports Error When Separate TX and Duplex TX Are Assigned in the Same Transceiver Quad - The Quartus II Fitter Reports Error When Separate TX and Duplex TX Are Assigned in the Same Transceiver Quad Description For designs with the Enable PLL Reconfiguration option turned on and targeting Cyclone IV GX devices, the Quartus II Fitter reports an error when separate TX and duplex TX SDI instances are assigned in the same transceiver quad. This issue affects all designs targeting Cyclone IV GX devices with the Enable PLL Reconfiguration option turned on. The design cannot be fitted in the device. Resolution Uses separate RX and TX SDI instances to fit more than 1 SDI transmitter in a transceiver quad. This issue will be fixed in a future version of the SDI MegaCore function.
