Vivado/ModelSim - ModelSim fails on PLI (AXI BFM) with "Error: (vsim-3193)" and "Error: (vsim-PLI-3002)"


When launching ModelSim from the Vivado IDE to perform AXI BFM behavioral simulation, the following error is seen:

# ** Error: (vsim-3193) Load of "C:/ProgramsMore/Xilinx/Vivado/2013.4/ids_lite/ISE/lib/nt/libxil_vsim.dll" failed: Bad DLL format.
# ** Error: (vsim-PLI-3002) Failed to load PLI object file "C:/ProgramsMore/Xilinx/Vivado/2013.4/ids_lite/ISE/lib/nt/libxil_vsim.dll".


This error occurs when the .do file generated by Vivado points to the 64-bit version of libxil_vsim.dll as shown below:

vsim -voptargs="+acc" -t 1ps -pli "C:/Xilinx/Vivado/2013.4/ids_lite/ISE/lib/nt64/libxil_vsim.dll" -L unisims_ver -L unimacro_ver -L secureip -lib work cdn_axi_bfm_0 glbl.

If you use the 32-bit version of ModelSim, the .do file has to point to 32-bit version of the DLL file.
Starting from Vivado 2013.3, you can use the below Tcl command to tell the tool that the ModelSim version being used is 32-bit.

set_property MODELSIM.64BIT 0 [current_fileset -simset]

If this does not work, an alternative work-around to try is to replace the above line in the .do file with the following:

vsim -voptargs="+acc" -t 1ps -pli "C:/Xilinx/Vivado/2013.4/ids_lite/ISE/lib/nt/libxil_vsim.dll" -L unisims_ver -L unimacro_ver -L secureip -lib work cdn_axi_bfm_0 glbl.

After editing the .do file, follow the below process:

1. Open a cmd prompt.

2. Run the following command:
Set PATH=%PATH%;C:\Xilinx\Vivado\2013.4\ids_lite\ISE\lib\nt
3. Launch 32-bit ModelSim from the command prompt.
4. Run the modified .do file in the console of ModelSim using the following command:
