National Instruments PXIe-7971 PXI FPGA Module for FlexRIO

The PXIe-7971 (Part Number: 782953-01) K325T FPGA, 1.7 GB/s, is an FPGA Module for FlexRIO. In addition to the FlexRIO adapter modules built by National Instruments, NI Alliance Partners can build adapter modules with the same degree of performance, functionality, and integration. These modules are available as either standard or custom products. If users cannot find an adapter module that meets their application needs from National Instruments or an NI Alliance Partner, then it is possible to build a custom adapter module using the NI FlexRIO Adapter Module Development Kit (MDK). The NI PXIe-7971 has 132 single-ended I/O lines, which can be configured as 66 differential pairs as well.

The NI LabVIEW and the LabVIEW FPGA Module provide graphical development for FPGA devices on NI Reconfigurable I/O (RIO) hardware targets. The user can create embedded FPGA VIs that combine direct access to I/O with user-defined LabVIEW logic to define custom hardware.

While LabVIEW is an effective tool for FPGA programming, the user may have existing hardware description language (HDL) intellectual property (IP) that they must integrate into their NI FlexRIO hardware applications. There are three options for doing so. The first option is the IP Integration Node. This node provides a simple, inline interface to HDL IP and Xilinx CORE Generator XCO files. It features an automatic LabVIEW interface generation and the ability to generate cycle-accurate simulation models for host execution. Using the latest functionality, the user can run their LabVIEW FPGA VI on the host to ensure proper functionality before compiling it for the FPGA.
