Dear all, In /usrp3_rfnoc/top/x300/x300.v,we found that: `ifdef SFP0_AURORA assign sfp0_gt_refclk = aurora_refclk; assign sfp0_gb_refclk = aurora_refclk_bufg; assign sfp0_misc_clk = aurora_init_clk; `endif Except for SFP0_10GBE and SFP0_1GBE,what is the SFP0_AURORA?If we delete it,which would affect x310? best regards John

Hi John. Aurora is a protocol developed by Xilinx to transfer data over point-to-point serial links that is an alternative to 1 or 10 gigE. https://www.xilinx.com/products/design_resources/conn_central/grouping/aurora.htm If the SPF0_AURORA macro is not defined, which by default it is not, there is no need to delete any Verilog code manually. That is the purpose of ifdef statements in Verilog. -Robin On Wed, Dec 14, 2016 at 10:08 PM, john liu via USRP-users < usrp-users@lists.ettus.com> wrote: > Dear all, > In /usrp3_rfnoc/top/x300/x300.v,we found that: > > `ifdef SFP0_AURORA > assign sfp0_gt_refclk = aurora_refclk; > assign sfp0_gb_refclk = aurora_refclk_bufg; > assign sfp0_misc_clk = aurora_init_clk; > `endif > > Except for SFP0_10GBE and SFP0_1GBE,what is the SFP0_AURORA?If we delete > it,which would affect x310? > > best regards > John > > _______________________________________________ > USRP-users mailing list > USRP-users@lists.ettus.com > http://lists.ettus.com/mailman/listinfo/usrp-users_lists.ettus.com > >
