How can I resolve Quartus II software "HSSI_PMA_AUX" associated fitter errors when compiling with Stratix V, Arria V, and Cyclone V transceiver devices? - How can I resolve Quartus II software "HSSI_PMA_AUX" associated fitter errors when compiling with Stratix V, Arria V, and Cyclone V transceiver devices? Description Quartus® II software "HSSI_PMA_AUX" associated fitter errors when compiling with Stratix® V, Arria® V, and Cyclone® V transceiver devices are typically associated with the transceiver reconfiguration controller IP. If you see Quartus II software "HSSI_PMA_AUX" fitter errors when compiling with Stratix V, Arria V, and Cyclone V transceiver devices you should double check the following key areas in your design. Check that you have connected up your reconfig_to_xcvr and reconfig_from_xcvr busses between the transceiver and reconfiguration controller correctly. Ensure that all transceiver IP in your design are connected to a reconfiguration controller. If one transceiver is connected to a reconfiguration controller, all transceivers must be. Ensure that you do not exceed more than one reconfiguration controller IP instance per transceiver half-block (bottom-three, or top-three channels in a transceiver bank). You can refer to the "Transceiver Reconfiguration Controller to PHY IP Connectivity" chapter of the transceiver PHY IP Userguide for further information. If you have more than one reconfiguration controller IP in your design that share a common Calibration Block, ensure that they have a common mgmt_clk_clk clock source. You can refer to the "Calibration Block Boundary" section of the Transceiver Architecture in Stratix V Devices chapter of the Stratix V GX handbook for details of Calibration Block boundaries. If you are using PCI Express CvP, you should also ensure that you adhere to the following advice on reconfiguration controller mgmt_clk_clk clock source requirements.
