5.1.7. Building an FPGA Bitstream for the PCIe Design Example
- You must have a license for bitstream generation of the FPGA AI Suite IP.
- You must have a specific version of Quartus® Prime Pro Edition installed:
- The PCIe design example for Agilex™ 7 devices requires Quartus® Prime Pro Edition Version 22.4 or later. This document assumes that Version 25.3 is used.
- You must have the following paths included in your $PATH environment variable:
- quartus/bin
- qsys/bin
If you do not have a license for 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 Design Example for Agilex™ 7 Devices
cd $COREDLA_WORK/demo
dla_build_example_design.py build agx7_de10_pcie \
$COREDLA_ROOT/example_architectures/AGX7_Performance.arch \
--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 FPGA AI Suite PCIe Design Example for Agilex 7 Devices.
dla_build_example_design.py --helpFor a list of options supported by an action, run the following command:
dla_build_example_design.py <action> --helpFor example, the dla_build_example_design.p build command provides a --seed option that you can use to vary the 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.
