Configurable FPGA Modules

The ADvantage Framework includes support for National Instruments PCI-783xR and PXI-783xR multifunction FPGA (field-programmable gate array) modules, and configuration of these modules using LabVIEW FPGA. This enables the FPGA-based intelligent IO modules to be used in real-time simulation.

FPGA-based models can be custom configured with complete control over the synchronization and timing of all signals, operations, and user-defined onboard decision-making logic. Digital lines can be individually configured as input, output, counter/timer, PWM, flexible encoder inputs, or user-defined communication protocols.

Applications

FPGA-based IO modules are an ideal tool for implementing complex analog and digital sensor emulators for complex real-time simulation problems. Example applications include:

• Vibrating cylinder pressure transducers
• Frequency-based speed transducers
• Encoder sensor emulation and measurement  
• Torque sensors

How does it work with ADvantage?

Using the LabVIEW-based FPGA modules you can create custom IO, ready to run in the high performance real-time world of ADvantage/rtX, without low-level hardware description languages or hardware board-level design and manufacturing capability.

FPGA modules are programmed stand-alone using National Instrument’s LabVIEW FPGA then added to an rtX simulator and connected to real-time simulation models using the ADvantage Framework.
