FPGA tests don't all work using Quartus

[adrianjhpc]

Summary

The board_test example (and other examples I've tested) from DirectProgramming/C++SYCL_FPGA/ReferenceDesigns fails on the part of the test that tries to extract the reference frequency using the aocl binedit functionality.

Version

Report oneAPI Toolkit version and oneAPI Sample version or hash.

oneAPI version 2022.0.2 quartus version 20.4 oneAPI sample hash f6660eef7007d0acb7de1bce9c6e5844c6615a80

Environment

Intel Stratix 10, Bittware N520 MX

Steps to reproduce

cd ~/oneAPI-samples/DirectProgramming/C++SYCL_FPGA/ReferenceDesigns/board_test
mkdir build
cd build
cmake .. -DFPGA_BOARD=s10mx:p520_hpc_m210h_g3x16
make fpga
./board_test.fpga

Observed behavior

When compiled and run the board_test.fpga executable fails, with this output at the end of the run:

*****************************************************************
*******************  Kernel Clock Frequency Test  ***************
*****************************************************************

terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_M_construct null not valid

Digging into the code it is because this functionality:

   std::string temp_cmd = "aocl binedit " + kBinaryName + " print .acl.quartus_report";
   const char *open_cmd_rep = temp_cmd.c_str();

Doesn't actually work. The executable (board_test.fpga) does not have anything to report when using 1aocl binedit board_test.fpga list, i.e. it produces an empty output:

Sections in package file:

This can be fixed by changing the command to this:

   std::string temp_cmd = "aocl binedit " + kBinaryName + ".prj/base.aocx" + " print .acl.quartus_report";
   const char *open_cmd_rep = temp_cmd.c_str();

Which then can be used to extract the reference FPGA frequency.

I can commit this as a pull request.

Expected behavior

The board_test to run without issues.

Please upgrade your OneAPI and FPGA add-on version to the latest and have a try. Reference: https://www.intel.com/content/www/us/en/docs/oneapi/programming-guide/2023-0/obtain-fpga-hardware-image-information.html
