Discrepancy (likely typo) between Coregen IP instantiate in eth_gth_phy_quad.v line 233 in example/HXT100G/fpga/rtl/. Component name as per .xco is ten_gig_eth_pcs_pma_v2_6_v6gth_wrapper, while the substantiation refers to ten_gig_eth_pcs_pma_v2_6_v6gth_wrapper_QUAD. Change instantiation to match .xco as a solution?
