Speedgoat FPGA Support with HDL Workflow Advisor

Introduction

Simulink^® Real-Time™ and HDL Coder™ enable you to implement Simulink algorithms and configure I/O functionality on Speedgoat field programmable gate array (FPGA) boards. For an example that shows the development workflow for FPGA I/O boards, see FPGA Programming and Configuration (Simulink Real-Time). You do not use these blocks outside of HDL Coder HDL Workflow Advisor.

To use these blocks, open HDL Coder HDL Workflow Advisor and use it to generate a Simulink Real-Time interface subsystem. See FPGA Programming and Configuration (Simulink Real-Time).

The subsystem mask controls the block parameters. Do not edit the parameters directly. The FPGA I/O board block descriptions are for informational purposes only.

Speedgoat FPGA IO Module Support

Speedgoat I/O FPGA boards are sold as part of Speedgoat target computer systems. Simulink Real-Time supports the following Speedgoat (www.speedgoat.com) FPGA IO modules.

IO Module Name Description Remarks

IO Module Name	Description	Remarks
`Speedgoat IO331`	The Speedgoat IO331 is a field-programmable gate array (FPGA) board that provides 64 bidirectional LVCMOS or 32 bidirectional LVDS I/O lines. This board is based on a Xilinx^® Spartan^® 6 chip with 147,333 logic cells. The Speedgoat IO331 is the base board. The Speedgoat IO331-6 is the AXM-A75 A/D converter, an add-on to the Speedgoat IO331.	Warning `Speedgoat IO331` and its variant `Speedgoat IO331-6` will no longer be supported in R2020b with the `Simulink Real-Time FPGA I/O` workflow. You can still run the workflow for these IO modules in R2020a. In R2020b, use `Speedgoat IO333-325K` or a later Speedgoat IO module that is based on Xilinx Vivado^®.
`Speedgoat IO333`	The Speedgoat IO333 is a field-programmable gate array (FPGA) board based on a Xilinx Kintex^® 7 chip with 325k logic cells. HDL Coder HDL Workflow Advisor supports the Speedgoat IO333-325K-06 configuration. For more information, see Speedgoat HDL Coder Integration Package for the IO333-325K at www.speedgoat.com/help.	–

Speedgoat IO331

The Speedgoat IO331 is a field-programmable gate array (FPGA) board that provides 64 bidirectional LVCMOS or 32 bidirectional LVDS I/O lines. This board is based on a Xilinx^® Spartan^® 6 chip with 147,333 logic cells.

The Speedgoat IO331 is the base board. The Speedgoat IO331-6 is the AXM-A75 A/D converter, an add-on to the Speedgoat IO331.

Warning

Speedgoat IO331 and its variant Speedgoat IO331-6 will no longer be supported in R2020b with the Simulink Real-Time FPGA I/O workflow. You can still run the workflow for these IO modules in R2020a. In R2020b, use Speedgoat IO333-325K or a later Speedgoat IO module that is based on Xilinx Vivado^®.

Speedgoat IO333

The Speedgoat IO333 is a field-programmable gate array (FPGA) board based on a Xilinx Kintex^® 7 chip with 325k logic cells.

HDL Coder HDL Workflow Advisor supports the Speedgoat IO333-325K-06 configuration. For more information, see Speedgoat HDL Coder Integration Package for the IO333-325K at www.speedgoat.com/help.

Workflow

To work with FPGAs in the Simulink Real-Time environment, you must:

Install HDL Coder and Xilinx design tools. For the specific tool and version required, see the board reference topic and the HDL Coder documentation.
Install the Speedgoat FPGA I/O board in the Speedgoat target machine.
Be familiar with FPGA technology. In particular, you must know the clock frequency and the I/O connector pin and channel configuration of your FPGA board.
Have experience using data type conversion and designing Simulink fixed-point algorithms.

To generate HDL code for your FPGA target, you do not need to have HDL programming experience.
