Why does the Arria®10 PCI Express BFM fail when using the Aldec simulator (Riviera Pro)? - Why does the Arria®10 PCI Express BFM fail when using the Aldec simulator (Riviera Pro)? Description Due to a problem with the file altpcietb_bfm_rp_gen3_x8.sv , you will see compilation errors when simulating with the Aldec Riviera Pro™ simulator. Resolution To work around this problem, edit the file altpcietb_bfm_rp_gen3_x8.sv so that "import altera_xcvr_functions_sv_bfm::*;" is located after the module declaration, as shown below: module sv_xcvr_plls #( parameter plls =1, // number of PLLs ... ); import altera_xcvr_functions_sv_bfm::*; This problem is not currently scheduled to be fixed in a future Quartus® Prime Software release.
