The XSG Utils Library offers ready-to-use function blocks for rapid control prototyping (RCP) or hardware-in-the-loop (HIL) simulation projects. The library gives users of real-time FPGA applications enhanced function blocks for implementing their own projects.
Completely open models for Simulink® and
Xilinx® System Generator (XSG)
Fixed-point and floating-point implementation
Ready-to-use ControlDesk instruments
The dSPACE XSG Utils Library offers users of real-time FPGA applications enhanced function blocks for implementing their own projects. The library is completely open and can be used in rapid control prototyping (RCP) projects as well as for hardware-in-the-loop (HIL) simulation.
Due to the generic programming, the library can be applied to all freely programmable dSPACE real-time FPGA platforms.
The dSPACE XSG Utils Library contains essential, often needed function blocks for FPGA programming as fixed-point and floating-point implementation. These included blocks provide high quality functions that are available in the standard Simulink library for processor-based implementations. The high-quality function blocks are ready to use and easy to adapt to your project, so they greatly facilitate your FPGA programming. They range from enhanced I/O, scope, and look-up table functions to an average calculator, sine generator, and wavetable encoder.
The XSG Utils Library offers pre-built custom instruments that enable quick access to the most used functions out of ControlDesk (for more information, please see relevant product information).
The XSG Utils Library is available in two versions:
For comprehensive development projects, both versions are needed.
Look-up Table (1-D, 2-D, and 3-D)
I/O Access Functions
UART (RX & TX)
Sine or Cosine
Three phase PWM generators with three modes: motor control, phase shifted, and user defined
|Scope||Captures 8 (out of 16) high-frequency signals within the FPGA clock rate and sends the captured data synchronously to the processor, where it can be displayed and stored in instruments such as the ControlDesk plotters.|
|PWM Measurement||Measures the dead time (time between HSD and LSD), high time, and period time of a single-phase or three-phase PWM signal.|
|PWM Generator||Generates an aligned PWM signal (single-phase and three-phase). The dead time and the duty cycle can be configured at runtime.|
|Look-up Table||Configures the accuracy of the table, and the minimum and maximum data values to be covered. Linear interpolation algorithms or the Use Input Below method can be configured online: 1-D, 2-D, and 3-D look-up tables are available. If required, the tables can be updated at runtime.|
|I/O Access Functions||Enables flexible programming and run-time parameterization of the onboard FPGA I/O as well as the stimulus mode.|
