Why am I seeing Riviera* simulation failures for the F-tile Ethernet Hard IP with Auto-Negotiation and Link Training (AN/LT) and Dynamic Reconfiguration enabled designs? - Why am I seeing Riviera* simulation failures for the F-tile Ethernet Hard IP with Auto-Negotiation and Link Training (AN/LT) and Dynamic Reconfiguration enabled designs? Description Due to a problem in the Quartus® Prime Pro Edition software version 25.1.1, you may see Riviera* simulation failures for the F-tile Ethernet Hard IP with Auto-Negotiation and Link Training (AN/LT) and Dynamic reconfiguration enabled designs. This failure is seen for 400GE-8 and 100GE-4 AN/LT Dynamic Reconfiguration example designs. Resolution For workaround, go to your ‘< design_example_dir>\example_testbench >’ folder and update the ‘ run_rivierasim.do ’ script as below: 1) Update the below line From : set USER_DEFINED_VERILOG_COMPILE_OPTIONS "+define+BK_FASTSIM_MODEL -err VCP2675 W1 To : set USER_DEFINED_VERILOG_COMPILE_OPTIONS "+define+INTC_SIM_AN_LT_ENABLE +define+GDR_TURNOFF_FASTSIM -err VCP2675 W1 2) Update the below line From : vlog +define+DR_F_GAVMM_SPEEDUP basic_avl_tb_top.sv eth_f_hw.v -f ./common_files_list.f To : vlog basic_avl_tb_top.sv eth_f_hw.v -f ./common_files_list.f This problem is scheduled to be fixed in a future release of the Quartus® Prime Pro Edition software.
