cannot launch modelsim software from quartus tool

Hi @NGoud​ ,

Configure Quartus II to work with ModelSim-Altera in native link mode:

· On the Tools menu, click Options. The Options dialog box appears.

· In the General list, select EDA Tool Options.

· For ModelSim-Altera, type the path or browse to the directory containing ModelSim-Altera. The directory should be located under the Altera directory, e.g. C:\<Quartus installation directory>\\modelsim_ase\win32aloem

· Select OK.

Also try by stetting PATH environment variable PATH=C:\<Quartus installation directory>\modelsim_ase\win32aloem.

Which version and edition of quartus are you using?

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

Regards

Anand
