请教大家一下~我想实现两块FPGA开发板之间的通讯,使用光模块QSFP,在对芯片Stratix V 的收发器通道进行配置时出现了问题,我用的IP核是Stratix V Transceiver Native PHY v13.0,使用QuartusII13.0进行编译,错误提示是:Error: HSSI PMA TX Buffer node 'xcvr_native_phy_ip:xcvr_native_phy_ip_inst|altera_xcvr_native_sv:xcvr_native_phy_ip_inst|sv_xcvr_native:gen_native_inst.xcvr_native_insts[0].gen_bonded_group_native.xcvr_native_inst|sv_pma:inst_sv_pma|sv_tx_pma:tx_pma.sv_tx_pma_inst|sv_tx_pma_ch:tx_pma_insts[0].sv_tx_pma_ch_inst|tx_pma_ch.tx_pma_buf.tx_pma_buf' is not properly connected on the 'DATAOUT' port. It must be connected to one of the valid ports listed below.
Info: Can be connected to I port of stratixv_io_obuf WYSIWYG
Error: Input port REFIQCLK0 of xcvr_native_phy_ip:xcvr_native_phy_ip_inst|altera_xcvr_native_sv:xcvr_native_phy_ip_inst|sv_xcvr_native:gen_native_inst.xcvr_native_insts[0].gen_bonded_group_native.xcvr_native_inst|sv_pma:inst_sv_pma|sv_rx_pma:rx_pma.sv_rx_pma_inst|rx_pmas[0].rx_pma.cdr_refclk_mux0 atom must be connected when parameter cdr_refclk_select is set to 'ref_iqclk0''
Info: Must be connected
大家做过类似的么?这个问题怎么解决呢?

哥们,我也遇到了一样的问题,你的解决了吗?呼唤解决方法,到底哪儿出了问题?
我也遇到了这个问题!
但是已经解决。
原因是我在例化jesd_ip的顶层文件中做了如下赋值:
assign alldev_lane_aligned =dev_lane_aligned;
assign rx_serial_data = tx_serial_data;
assign tx_sync_n = rx_dev_sync_n;
修改方案:
将以上六个信号作为顶层端口,在tb文件中完成lookback赋值,错误解决!
