FPGA tests don't all work using Quartus
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.
