FPGA PWM Signal Generator — Labview-fpga Code
Generates a PWM output signal on an FPGA using LabVIEW G pseudo-code.
// FPGA VI pseudo-representation
int dutyCycle = 50; // 50 percent
Loop FPGAClock
{
int clockPhase = GetClockPhase();
WriteFPGAOutput("PWMOut", (clockPhase < dutyCycle) ? 1 : 0);

LabVIEW FPGA is a National Instruments platform that allows developers to design and deploy custom FPGA-based hardware logic using graphical programming (G), enabling high-performance, deterministic, and parallel execution for instrumentation, control, and embedded systems.
Primary Use Cases
- ▸High-speed data acquisition
- ▸Deterministic control loops
- ▸Custom instrumentation and test equipment
- ▸Real-time signal processing
- ▸Embedded control with CompactRIO and FlexRIO
Notable Features
- ▸Graphical programming for FPGA
- ▸Hardware-timed deterministic execution
- ▸Integration with LabVIEW host VIs
- ▸Support for DMA FIFO and registers
- ▸Simulation and debugging tools for FPGA
Origin & Creator
Developed by National Instruments (NI), USA-leader in test, measurement, and automation solutions.
Industrial Note
Extensively used in automated test equipment (ATE), aerospace, defense, particle accelerators, high-speed data acquisition, embedded control systems, and real-time signal processing.
