Why does the simulation of my Altera® AXI BFMs fail? - Why does the simulation of my Altera® AXI BFMs fail? Description In the Quartus® Prime Pro Edition Software, a VHDL testbench generated by Visual Designer Studio or Platform Designer using Altera® AXI BFM will error out. The Altera AXI BFMs only support testbenches generated in Verilog HDL or System Verilog HDL. In the Siemens* Questa* Simulator, the error message may be similar to this: ** Error: <file name>.vhd: (vcom-1598) Library "<library name>" not found. Resolution To avoid this problem, generate the testbench in Verilog HDL or System Verilog HDL.
