Create real-time FPGA applications with Simulink Real-Time™ and Speedgoat FPGA I/O modules. This solution enables specialized reconfigurable I/O or algorithm acceleration of parts of your real-time application.

Highlights include:

  • Design floating- and fixed-point applications in Simulink
  • Place Speedgoat Simulink® blocks that implement I/O and protocol functionality for analog and digital I/O, PWM generation and capture, or encoder measurement and simulation (quadrature, SSI, SSI2, EnDat 2.2, BiSS)
  • Connect with your hardware by selecting the required physical hardware interfaces provided by FPGA-based I/O modules from Speedgoat, and interconnect FPGA-based I/O modules and additional external circuitry using SPI and I2C Simulink blocks
  • Create real-time applications from Simulink using HDL Coder™ and Simulink Coder™
  • Run synchronized real-time applications on FPGAs and multicore CPUs
  • Test your designs using instrumentation, monitoring, logging, and automation functionality provided by Simulink Real-Time

The following table provides an extract of supported FPGA-based I/O modules and software functionality from Speedgoat for use with HDL Coder and Simulink Real-Time™. Support for Virtex 6, Kintex 7, and eight FPGAs is available or in development.

IO33x Software support for HDL Coder from Speedgoat

Netlists

While Simulink is an ideal environment to model and simulate control designs, vision systems, or plant simulations, it’s not primarily intended to implement protocols.

Speedgoat provides you with Simulink blocks and corresponding netlists that allow you to simply drag and drop protocol support such as for PWM generation and capture, encoder measurement and simulation, or SPI and I2C.

When you create HDL code from your application using HDL Coder, your real-time application design in Simulink and your Speedgoat netlists will be combined to a single bitstream.
