After trying your recommendations, I realized that I cannot create a regular Quartus project because my machine does not run Quartus well as it is too old. When I tried the same procedure on a newer machine I was able to make HLS work. Thanks a lot for your help. Re: High Level Synthesis (HLS) Counter Example HLS Generate testbench QSYS system FAILED Hello, I have a dedicated directory named Altera and I have all the installation files in that directory. The files in that directory are cyclonev-21.1.1.850.qdz HLSProSetup-22.2.0.94-windows.exe QuartusLiteSetup-21.1.1.850-windows.exe QuartusProgrammerSetup-21.1.1.850-windows.exe QuestaSetup-21.1.1.850-windows.exe I ran QuartusLiteSetup-21.1.1.850-windows.exe installed everything except for hls by choosing the installtion step. I couldn't install HLS because it didn't show up during the installation. Then I installed HLS after the installation of Quartus is done. Now that you asked me to check if CycloneV is installed, I tried to ran QuartusLiteSetup exe file and by choosing upgrade I checked that CycloneV is installed. As I have Quartus Prime Lite, I don't have access to Arria10 devices so I didn't even downloaded them. When I try it, I get "Arria10 is not supported in Quartus Standard Edition" error. When I check the fpga download center Quartus Prime Lite 21.1 individual files page, I couldn't see Arria10 qdz file. Would you like me to download Arria10 qdz file from other versions of Quartus Prime and try to install it and try hls with Arria10 after installing it? Thanks for answering, Anıl High Level Synthesis (HLS) Counter Example HLS Generate testbench QSYS system FAILED I have a Windows 10 machine. I installed Quartus Prime Lite 21.1.1 and HLS Pro 22.2. I know that I only have access to CycloneV To test HLS, I tried the counter example and followed the steps in Section 2.2 of the Getting Started Guide . When I execute "build.bat test-x86-64", everything is fine. After modifying the build.bat file so that -march=CycloneV instead of -march=Arria10, I tried "build.bat test-fpga" and get the following output: i++ -march=CycloneV counter.cpp -o test-fpga.exe HLS Generate testbench QSYS system FAILED. See c:/Users/bente/Desktop/counter/test-fpga.prj/debug.log for details. Run test-fpga.exe to execute the test. I also tried it with some other easy multiplication example and after I enter the command "i++ -march=CycloneV mult.cpp -o mult.exe", I get the same error. Is there anybody who knows what this error means? Also, I attach debug.log file in the hopes that it may be of some help. Thanks in advance Solved
