ModelSim crashes with Xilinx Vivado 2020.1

If you want to run Xilinx design in Intel FPGA, You first need to do migration before you can do any simulation, you can look into the document here on how to do the migration: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an307.pdf

Look for area:

3. FPGA Tools Comparison 4. Xilinx to Intel FPGA Design Conversion

After that, you can just launch the modelsim mention in

3.3.12. Simulation
