Description
Due to a problem in the Quartus® II software version 13.0, after installation, the default path to the ModelSim-Altera software is incorrectly set to:
<install_directory>\win32aloem (for example, C:\altera\13.0.0.156\win32aloem)
Resolution
To correct this issue, open the Options dialog box by selecting Options on the Tools menu. Select the EDA Tool Options category, and change the path to the following:
<install_directory>\modelsim_ase\win32aloem (for example, C:\altera\13.0.0.156\modelsim_ase\win32aloem)
This problem is fixed beginning with the Quartus II software version 13.0 SP1.
