# ** Error: (vsim-3197) Load of "<user path>/simulation/submodules/bytestream_pli.dll" failed: <user path>/simulation/submodules/bytestream_pli.dll: invalid ELF header.

Due to a problem in the Quartus® II software versions 11.1 and later, you may see this error when simulating your design using ModelSim SE software. You may also see the following error message:

# ** Error: (vsim-PLI-3002) Failed to load PLI object file "<user path>/simulation/submodules/bytestream_pli.dll".

This error is caused by an incorrect line in the msim_setup.tcl script created to run the ModelSim SE software.

To work around this problem, comment out the following line from the msim_setup.tcl script file.

"-pli /submodules/bytestream_pli.dll"

This problem is scheduled to be fixed in a future release of the Quartus II software.
