6.8. Building an FPGA Bitstream for the PCIe Example Design
- You must have a license for bitstream generation of the Intel® FPGA AI Suite IP.
- You must have a specific version of Intel® Quartus® Prime Pro Edition installed:
- The PCIe-based design example for Intel® Arria® 10 requires Intel® Quartus® Prime Pro Edition Version 19.2.
- The PCIe-based design example for Intel Agilex® 7 devices requires Intel® Quartus® Prime Pro Edition Version 22.4.
- You must have the following paths included in your $PATH environment variable:
- quartus/bin
- qsys/bin
If you do not have a license for Intel® FPGA AI Suite, the generated IP has a built-in inference-count limitation. Any inference operations that occur after the limit is reached generate an error message that indicates that a license is required. To reset the inference count limit, you must reprogram the bitstream onto the FPGA device.
Building an FPGA Bitstream for the PCIe-Based Design Example for Intel® Arria® 10 Devices
cd $COREDLA_WORK/demo dla_build_example_design.py \ -a $COREDLA_ROOT/example_architectures/A10_Performance.arch \ --build -ed 1 \ --build-dir build_A10_Performance \ --output-dir $COREDLA_WORK/demo/my_bitstreams
You must include the -n 1 option when you build the A10_FP16_Example.arch architecture because the FPGA device on the Intel® PAC with Intel® Arria® 10 GX FPGA has enough DSPs only to build a single instance of this architecture.
If you want to vary the Intel® Quartus® Prime random seed, specify the --seed option as part of the dla_build_example_design.py command.
dla_build_example_design.py --help
This commands places the bitstreams into the my_bitstreams directory. The bitstream is named A10_Performance.gbs.
After the bitstream is built, you must program it onto the FPGA following the instructions in section Programming the FPGA Device.
Building an FPGA Bitstream for the PCIe-Based Design Example for Intel Agilex® 7 Devices
cd $COREDLA_WORK/demo dla_build_example_design.py \ -a $COREDLA_ROOT/example_architectures/AGX7_Performance.arch \ --build -ed 3 -n 4 \ --build-dir build_AGX7_Performance \ --output-dir $COREDLA_WORK/demo/my_bitstreams
If the AOCL_BOARD_PACKAGE_ROOT environment variable is not set, the dla_build_example_design.py command returns an error message. To set this environment variable, review the instructions in Additional Software Prerequisites for the PCIe-based Design Example for Intel Agilex 7 Devices.
dla_build_example_design.py --helpThe dla_build_example_design.py command provides a --seed option that you can use to vary the Intel® Quartus® Prime random seed.
This commands places the bitstreams into the my_bitstreams directory. The bitstream is named AGX7_Performance.sof.
After the bitstream is built, you must program it onto the FPGA following the instructions in section Programming the FPGA Device.
