We are now able to checkout the vsim license connecting with AOCL after setting the correct $PATH But , unfortunately , we are seeing that once the vsim simulation starts , the Modelsim GUI window exists automatically . The modelsim GUI provides some error message , but we are not able to retrieve from some log files . we are stuck now and need help . We also , have the below queries related to running the Modelsim Project Files 1. Can we run Modelsim on the generated RTL files explicitly ? currently , we are using -simulator along with the .cl files to generate + simulate 2. We have used -v in the aocl command line to enable verbosity , but looks like vsim log files are not getting generated somehow . We also want to use vsim -l kind of inputs to generate the compile , simulate logs for further analysis 3. We don't want exit the VSIM GUI window if there is any ERROR occurred . Above debug aids will be very helpful to analyze the issues further Thanks a lot for the help Regards Deb Re: Error While running AOCL with -simulator switch Is the issue something to do with the Modelsim Installation related ? Do we need any specific setup before running the AOCL with -simulator option ? Error While running AOCL with -simulator switch Hi We are running simulation with OpenCL SDK . We used the -simulator option in-order to generated an .aocx file . We want to run and debug on Linux kernel in a simulation mode . We used Intel® Quartus® Prime Design Suite: 21.1. We are seeing some error related to vsim installation . Error Snippet as attached . Can You please help if something got missed with the setup ? Thanks Deb
