I don't know offhand if we have another Linux machine available to install 21.4, but I can find out. Thanks, Lacey Re: HLS run Quartus compile FAILED with following error "qsh_flowengine.tcl" unsuccessful Hello @BoonBengT_Altera , Sorry for the delay (I was out sick with covid). Our machine is running Red Hat Enterprise Linux Server version 7.9 (Maipo) and the Quartus version is 21.4. Thank you, Lacey Re: HLS run Quartus compile FAILED with following error "qsh_flowengine.tcl" unsuccessful Hi @BoonBengT_Altera , Thank you for this suggestion. I rebooted the computer and ran the tutorial exactly as I did in this post while monitoring the RAM usage. The system RAM usage topped out at 9 GB. The computer has 125 GM of RAM, so unfortunately I don't think this is the problem. Thank you, Lacey Re: HLS run Quartus compile FAILED with following error "qsh_flowengine.tcl" unsuccessful Hello BB, Thanks for checking in. The problem hasn't been solved yet. Regarding your suggestions, I was able to create a project with Arria10 devices QuestaSim is installed Running init_hls.sh shows that all of the steps were successful (shown in the attached logfile) I haven't had the chance to try reinstalling. Thank you, Lacey Re: HLS run Quartus compile FAILED with following error "qsh_flowengine.tcl" unsuccessful Hello, We tried to compile "tutorials/best_practices/optimize_ii_using_hls_register" on a Linux machine. When I run "make" I get this message in the terminal: i++ -march=Arria10 --quartus-compile -ghdl part_1_implemented_using_memory_module.cpp -o part_1_implemented_using_memory_module HLS run Quartus compile FAILED. See /home/jlrainbolt/tutorials/best_practices/optimize_ii_using_hls_register/part_1_implemented_using_memory_module.prj/debug.log for details. make: *** [part_1_implemented_using_memory_module] Error 1 In "part_1_implemented_using_memory_module.prj/debug.log" (attached), the error message is Error (23031): Evaluation of Tcl script /opt/intelFPGA_pro/21.4/quartus/common/tcl/internal/qsh_flowengine.tcl unsuccessful If I open "part_1_implemented_using_memory_module.prj/quartus/quartus_compile.qpf" in Quartus and press the play button, the compilation fails with no error messages shown (as in the attached screenshot). Thank you!
