This file contains important information about the LabVIEW FPGA Module, including system requirements, installation instructions, upgrade and compatibility issues, known issues, and a partial list of bugs fixed for this release.
With the LabVIEW FPGA Module, you can create VIs that run on NI FPGA targets, such as reconfigurable I/O (RIO) devices. The FPGA Module helps you design complex systems by providing a highly-integrated development environment, a large ecosystem of IP libraries, a high-fidelity simulator, and debugging features. The FPGA Module also includes the FPGA Compile Farm Server. You can use the FPGA Compile Farm Server to offload compiles to dedicated computers.
The development computer is a PC or NI PXI/PXI Express system on which you install LabVIEW and the FPGA Module. You can also install the Xilinx compilation tools on your development computer to compile LabVIEW FPGA VIs locally. However, if the FPGA design or target requires more than 2 GB of memory, NI recommends you install the Xilinx compilation tools on a separate computer. This computer is referred to as the remote compile worker.
Visit ni.com/info and enter the Info Code XilinxCompileTools for more information about the NI hardware supported by each Xilinx compilation tool.
The development computer must meet the following system requirements:
1 Memory requirements vary according to both the FPGA target and the FPGA VI you create for that target.
2 You must use a 64-bit OS to address 4 GB of RAM.
3 NI software installs VC2015 Runtime and .NET 4.6.2. Windows 8.1 and Windows Server 2012 R2 require Microsoft updates to support these items. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.
4 NI software is signed with a SHA-256 certificate. Windows 7 SP1, Windows Embedded Standard 7 SP1, and Windows Server 2008 R2 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.
Refer to the LabVIEW Readme for additional system requirements and supported operating systems for LabVIEW.
If you install the FPGA Compile Farm Server on a separate computer, you can configure that computer to be a remote compile farm server. If you install the Xilinx compilation tools on a separate computer, you can configure that computer to be a remote compile worker.
Refer to the Setting Up a Remote Compile Farm Server or Compile Worker section of this document for information about setting up and using a local or remote compile farm server or compile worker. Visit ni.com/info and enter the Info Code XilinxCompileTools for more information about the NI hardware supported by each Xilinx compilation tool.
You can use either a Windows or Linux computer as a compile worker. Refer to the Xilinx Compilation Tools Readme for information about the minimum system requirements.
The remote compile farm server must meet the following minimum system requirements:
Note In 2016 the FPGA Compile Farm Server dropped support for Windows Vista, Windows XP, Windows Server 2003, and installations of Windows 7 without any service packs. The LabVIEW 2020 FPGA Compile Farm Server will not install or run on an unsupported OS. Refer to FPGA Module Drops Support for Windows 7 (32- and 64-Bit), Windows Server 2008 R2, and All 32-Bit Windows Operating Systems in 2021 for information about future OS support.
1 NI software installs VC2015 Runtime and .NET 4.6.2. Windows 8.1 and Windows Server 2012 R2 require Microsoft updates to support these items. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.
2 NI software is signed with a SHA-256 certificate. Windows 7 SP1, Windows Embedded Standard 7 SP1, and Windows Server 2008 R2 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.
This section provides information about installing the FPGA Module and related components.
Note If you are upgrading from a previous version of LabVIEW, you must install the LabVIEW 2020 FPGA Module before mass-compiling existing FPGA VIs. Otherwise, some FPGA-specific VIs might have mutation issues.
NI installs the FPGA Module using NI Package Manager. If you do not already have NI software installed, the FPGA Module installs NI Package Manager to handle the installation of your NI software. Visit ni.com/r/NIPMDownload to download NI Package Manager. Refer to the NI Package Manager Manual for more information about installing, removing, and upgrading NI software using NI Package Manager.
To install LabVIEW and the FPGA Module using the LabVIEW Platform media, complete the following steps:
In addition to installing program files and documentation in the LabVIEW directory, the installer also puts files from Xilinx in the x:\NIFPGA directory, where x is the drive on which you installed LabVIEW. The FPGA Module uses these files to compile FPGA VIs into code that runs on an FPGA target.
You can use the LabVIEW Platform media to install the FPGA Compile Farm Server to offload compiles to dedicated computer. You must install the FPGA Compile Farm Server separately on any remote machine that you want to use to manage your compilations. Also, you must install the Xilinx compilation tools on any machine that you want to use as a remote compile worker. Visit ni.com/info and enter the Info Code XilinxCompileTools for more information about the NI hardware supported by each Xilinx compilation tool.
NI also offers the LabVIEW FPGA Compile Cloud Service to increase the development efficiency by offloading compile jobs to multiple computers in a cloud environment. Visit ni.com/trycompilecloud for information about the LabVIEW FPGA Compile Cloud.
The FPGA Module (64-bit) provides access to more memory than the FPGA Module (32-bit) can provide. The FPGA Module (64-bit) is available in English only.
