To run an Intel® HLS Compiler design example on Linux systems:

1. Start a terminal session and initialize the Intel® HLS Compiler environment.
   For instructions how to initialize the environment, see Initializing the Intel HLS Compiler Pro Edition Environment.
2. Navigate to the <quartus_installdir>/hls/examples/<design_example_name> directory, where <quartus_installdir> is the directory where you installed Intel® Quartus® Prime software.
   For example, /home/<username>/intelFPGA_pro/21.4 .
3. Run the make test-x86-64 command. This command compiles the C++ source code to an x86-64 binary executable. Then, run the generated executable on your CPU.
   Expected outcome after you run the make test-x86-64 command:

   • The console displays the command used to generate the binary. For example, i++ -march=x86-64 -o test-x86-64 <source_files> .
   • The HLS compiler creates an executable file (for example, test-x86-64) in the current working directory.
   • The console displays the output of the executable to signify a successful execution.

   $ make test-x86-64
   i++ MGS.cpp QRD_Testbench.cpp TestbenchHelpers.cpp  -ffp-contract=fast -ffp-reassociate -march=x86-64 -o test-x86-64
   +----------------------------------------+
   | Run ./test-x86-64 to execute the test. |
   +----------------------------------------+

4. Run the make test-fpga command. The command compiles the C++ source code to a hardware executable and then runs a simulation of the generated HDL.
   Expected outcome after you run the make test-fpga command:

   • The console displays the command it uses to generate the testbench binary and the contents of the project directory. For example, i++ -march="<FPGA_family_or_part_number>" <source_files> -o test-fpga.
   • The HLS compiler creates a .prj directory (for example, test-fpga.prj) in the current working directory.
   • The console displays the output of the executable to signify a successful execution.

   $ make test-fpga
   i++ MGS.cpp QRD_Testbench.cpp TestbenchHelpers.cpp  -v -ffp-contract=fast -ffp-reassociate -march=Arria10 -o test-fpga
   Target FPGA part name:   10AX115U1F45I1SG
   Target FPGA family name: Arria 10
   Target FPGA speed grade: -2
