Wavform Simulator Error: Invalid Licese Environment - Wavform Simulator Error: Invalid Licese Environment I installed Quartus II 24.1 Lite Edition. When using waveform simulator, I found the error: *** Running the ModelSim simulation **** c:/altera_lite/24.1std/questa_fse/win64//vsim -c -do test.do ** Fatal: Failed to initialize licensing environment. License environment not set correctly. Unable to checkout a license. Vsim is closing. ** Error: Invalid license environment. Application closing. Error. Everything was fine before this error. I have allready fixed my license to Quartus II in options-License Setup.Maybe my question is too basic to be answered but I have tried every method I could think about. Thank you.

My problem is solved and thank you for your patience and notice. Replies: Re: Wavform Simulator Error: Invalid Licese Environment Any update on this? Do you able to simulate using the Questa Intel FPGA Starter Edition? Regards, Richard Tan Replies: Re: Wavform Simulator Error: Invalid Licese Environment Since you are using Quartus Lite, we have a quick start manual on how to run the Questa tool using the Nativelink simulation flow (only in Quartus Lite/Std edition). You can download the example design and give it a run. Once you are familiar with the simulation flow, try this with your own design and testbench. https://www.intel.com/content/www/us/en/docs/programmable/703090/21-1/simulation-quick-start.html Regards, Richard Tan Replies: Re: Wavform Simulator Error: Invalid Licese Environment Can you explain the process in detail? Replies: Re: Wavform Simulator Error: Invalid Licese Environment Seem like a tool limitation with the Simulation Waveform Editor. Try to run using our Questa Intel FPGA Starter Edition simulation tool. The tool should be able to provide the output data.

Replies: Re: Wavform Simulator Error: Invalid Licese Environment Questa Intel FPGA Edition Software required you to set up the LM_LICENSE_FILE environment variable. You may checkout the user guide below on how to set up the Questa license. https://www.intel.com/content/www/us/en/docs/programmable/683472/24-3-1/and-software-license.html Regards, Richard Tan Replies: Re: Wavform Simulator Error: Invalid Licese Environment Is your LM_LICENSE_FILE environment variable pointing to your license file?
