Can't launch Modelsim from Quartus - Can't launch Modelsim from Quartus When attempting to Tools -> Run simulation tool -> RTL Simulation, I get this error My EDA settings path is correct I've appended an additional '\' as per this thread https://forums.intel.com/s/question/0D50P00003yyQA2SAM/cant-launch-the-modelsimaltera-software?language=en_US I also have no spaces or brackets in the path. I can launch Modelsim fine on its own. the nativelink_simulation.rpt file is empty. Any ideas? Replies: Re: Can't launch Modelsim from Quartus Fixed! Thank you very much :) Replies: Re: Can't launch Modelsim from Quartus Go to Assignments > setting > EDA Tool Settings > Simulation. Change the Tool name to Modelsim-Altera and it should work.
