Hi Valery,

Can you try the solution provided in this old thread and let me know if it works for you?

Thanks,

Thank you very much for your response! I've seen this information but it involves the manual editing of the script which does not seem viable in my case. I'll try to describe what I actually do in detail.

I'd like to simulate the DDR3 SDRAM Controller using the Example Design that is generated with the following tool (cf. attachement).

The genenation completes successfully and I get the README file in the simulation folder. Then I perform all the actions as listed in the README file. When I run the simulation it starts successfully. Hoewever, when I click the "Break" button when the simulation is running I get the above mentioned errors (i. e. "path not found").

It is noteworthy to mention that $QUARTUS_INSTALL_DIR variable in the autogenerated msim_setup.tcl points to the correct location:

set QUARTUS_INSTALL_DIR "C:/intelfpga/18.1/quartus/"

Do I understand correctly that these errors should not display if I follow the recommendations from the README file?

Should I really set path_to_quartus variable in order to solve the problem? May this problem be connected to environment variables or libs installation?
