Can't launch Questa from Quartus - Can't launch Questa from Quartus I just installed Quartus (Lite edition) and Questa (starter edition). And Quartus is able to compile a small project, but when I try to launch Questa (Tools->Run Simulation Tool->RTL Simulation), I get a NativeLink error, pointing me to a nativelink_simulation rpt file, the rpt file says that the c:/intelfpga_lite/22.1std/quartus/common/tcl/internal/nativelink/modelsim.tcl is missing but it is not. It is in the correct location. attached is the rpt file. Please advise on how to solve the problem. Replies: Re: Can't launch Questa from Quartus Thank you for acknowledge the solution provided.

Replies: Re: Can't launch Questa from Quartus This is a known issue in Quartus lite 22.1. So you will need add a double quote on line 122 in the qnativelinkflow.tcl file located at the <Intel® Quartus® Installation Path>/quartus/common/tcl/internal/nativelink directory. From this : set questa_installation "$questa_fse_directory To: set questa_installation "$questa_fse_directory" Another forum thread with same issue: https://community.intel.com/t5/Intel-Quartus-Prime-Software/Error-while-trying-to-run-Questa-simulator/m-p/1466418#M77649
