[dsun01]

Dear Intel Support/FPGA Expert

I opened AN812 top_system.qsys with Quartus pro 21.3, using Platform Designer Generate Testbench, then I use Questa, change directory to top_system_tb/sim/mentor. do msim_setup.tcl. I will get the following error. 

can someone explain what this error means and how to fix this problem?

thank you, 

David

Hi David,

 Do you mind to share the file for me to check it? By reading the error message, it seems like the command in msim_setup.tcl is invalid. You may try to change this  command "top_system_tb::get_env_variables" in your script.

Thanks,

Ean
