HDL Coder Support Package for NI FPGA Hardware

HDL Coder™ Support Package for NI FPGA Hardware enables generating bitfiles for NI FPGA hardware from HDL Coder by providing LabVIEW FPGA integration.

This workflow allows you to perform the following actions:

• Map algorithm I/O to onboard interfaces
• Generate HDL code
• Generate a LabVIEW FPGA project and create a bitfile. Once created, you can upload this file to NI FPGA Hardware.

Note: This support package is functional for R2022b and later releases listed in the table below

Compile Server Considerations

• Local Compile Server – To install the recommended version of the Xilinx compilation tool, refer to Compatibility between Xilinx Compilation Tools and NI FPGA Hardware. Install the compilation tool from LabVIEW FPGA Compilation Tool.
• Network Compile Server – To set up a network compile server, refer to NI LabVIEW FPGA Compilation Options.
• LabVIEW FPGA Compile Cloud Service – To set up an account to use the cloud compile service, refer to Creating an Account for the NI LabVIEW FPGA Compile Cloud Service. For more details on Compile Cloud Service, refer to Compile Faster with the LabVIEW FPGA Compile Cloud Service.

Known Limitations

• Only supports VHDL.
• No support for double precision ports (single precision is supported).
• Only registers CPU-FPGA communication through Read/Write controls.
• No support for purely combinatorial circuits, such as circuits without clocks.
• Cannot connect array and complex ports to board I/O.
• Post code generation ports in VHDL entity that do not have a corresponding model port(e.g., clk_enable) will be mapped to registers.
• Save and Load Restore Point does not work.
• Auto-restore last exited session does not work.
• Only English LabVIEW is supported.
