Simulink-Programmable FPGA Modules

Many applications require high-frequency signal acquisition and generation, signal processing algorithms, and plant simulation and control with closed-loop rates of less than a microsecond. Simulink-programmable FPGA I/O modules use the latest Xilinx^® FPGAs to deliver the lowest latency connectivity and high-frequency closed-loop sample times.

Simulink-programmable FPGA I/O modules from Speedgoat are designed in close partnership with MathWorks^® to ensure seamless integration with MathWorks products such as Simulink Real-Time^™, Simscape^™ and HDL Coder^™ for automatic HDL code generation.

Simulink-programmable FPGA I/O modules can be combined with a vast range of FPGA code modules for off-the-shelf I/O and protocol functionalities, and scaled to your specific requirements.

Inter-module communication can be achieved through multi-gigabit, high-speed protocols, such as Xilinx Aurora.

Simulink-Programmable FPGA I/O Modules Selection Guide

To achieve very high closed-loop rates (up to multiple MHz) the FPGA I/O modules include their own local I/O in order to bypass the limitations of the relatively slow PCI bus. This local I/O is either integrated into the module or can be added as a plug-in. The Selection Guide below shows the wide range of analog, digital, and fiber optic transceivers available.

I/O module	FPGA chip	Logic cells	Front I/O lines	Rear I/O lines
IO332	Xilinx Artix-7	200k	Selectable front plug-ins	64 LVCMOS or 32 LVDS Selectable rear plug-ins 8 x MGT
