The PXI-6653
National Instruments (NI) announced that design and test engineers can now use the LabVIEW FPGA software with its two new PXI timing and synchronization modules for custom, user-defined applications, including custom triggering, system timing control, multidevice synchronization and high-speed analog counters.

The new PXI-6653 and PXI-6652 modules use the trigger bus, star trigger and system reference clock features of PXI to implement multidevice or multichassis synchronization. With the LabVIEW FPGA module, engineers can target the FPGA on the PXI-6653/2 modules to develop custom, user-defined applications that were previously impossible to implement with off-the-shelf hardware, said the press release.

According to NI, the new integration is possible with the latest version of the NI-SYNC driver softwareNI-SYNC 1.2, which is included with the PXI hardware and is available as a free download to engineers who already own the PXI module.

The combination of the LabVIEW FPGA module with the NI PXI-6653/2 timing and synchronization modules is suitable for a variety of industries, including ATE, automotive, military/aerospace and scientific research.

The LabVIEW FPGA module also works with the company's PXI- and PCI-based R series reconfigurable I/O devices, compact vision systems and the CompactRIO platform. NI added that it improves the efficiency and functionality of embedded FPGA applications.

The latest version features single-cycle while loops that execute multiple functions within a single 25ns "tick" of the 40MHz global clock. With this new feature, engineers can use LabVIEW to develop FPGA code that executes as efficiently as hand-coded VHDL. They also can reuse their existing VHDL code in LabVIEW FPGA applications with a new HDL interface node.
