OPAL-RT provides ARINC AFDX solution for Hardware-in-the-Loop (HIL) and rapid control prototyping (RCP) applications, such as full authority digital engine/electronic control (FADEC) and aircraft system components testing.
Based on a PCIe board, our solution connects OPAL-RT simulators to the ARINC AFDX avionics data bus, and facilitates the configuration of independent channels for transmission (TX) and reception (RX) at a bit rate up to 1,000 MBits/s.

AFDX (Avionics Full Duplex Switched Ethernet) is a communications network defined in the ARINC-664, Part 7 standard for the exchange of data between avionics subsystems. AFDX is based on ethernet technology and adapted to the avionics environment. The major components of avionics networks are the avionics subsystem (e.g., flight control system, GPS, TPMS, etc.) and the AFDX end system, which acts as an interface between various avionics subsystems via switched ethernet network. The major concepts of this protocol are full duplex, redundancy, determinism, high-speed performance, switched and profile network. The AFDX PCIe card will behave as a switch between end devices, capable of receiving and transmitting.
