Honored ContributorI'm revisiting this problem that I have had with the Modelsim-Altera simulation of this reference design. The errors caused from generating the BFMs were caused by the inclusion of the SV HIP Status Output Bridge. Removing this device from the design allows for their generation in Quartus 13.1, but problems still remain. Sourcing msim_setup.tcl in Modelsim-Altera, then entering 'ld_debug' and finally 'run -a' causes the simulation to start and eventually error out. The logs show three irregularities:
# ERROR: The attributes for bit 'rdynamic_sw' have illegal conflicting values # ERROR: Txelecidle not asserted in P1 state # FATAL: 97272 ns Current Link Speed is Unsupported # FAILURE: Simulation stopped due to Fatal error!# Break in Function ebfm_log_stop_sim at ./..//top_tb/simulation/submodules//altpcietb_g3bfm_log.v line 118 Did I miss a step in properly generating the simulation files? I'm not sure where to proceed from here. Thanks, Neophyte
