SmartDV’s AFDX 1G Switch IP is a fully featured Avionics Full-Duplex Switched Ethernet switch solution purpose-built for safety-critical avionics and aerospace SoC applications requiring deterministic, standards-compliant AFDX network switching. Fully compliant with ARINC 664 Part 7 and IEEE 802.3-2022, it delivers complete AFDX switch functionality at 10/100/1000 Mbps with frame filtering, Virtual Link traffic shaping, comprehensive TSN support, and ultra-low latency cut-through switching — providing a feature-complete AFDX network switch for next-generation avionics network infrastructure designs.
Designed to address the full breadth of AFDX switch requirements, the IP implements the complete ARINC 664 frame filtering mechanism covering Ethernet frame size validation (64 to 1518 bytes), Frame Check Sequence validity checking, frame length error detection, and Ethernet line size validation (84 to 1538 bytes), alongside Virtual Link Bandwidth Allocation Gap enforcement, traffic scheduling, frame replication and elimination, and class-based flow control across 8 traffic classes. Its independently configurable TSN features, detailed per-Virtual-Link statistics, programmable IPG and preamble length, and configurable transmit and receive FIFOs give avionics network infrastructure teams a spec-complete AFDX switch implementation suited for the most demanding safety-critical airborne network designs.
Built for design flexibility and silicon efficiency, the IP core is highly configurable for both ASIC and FPGA implementations, with a strong focus on area optimization, power management, and peak performance. Its fully synthesizable architecture, GMII/RGMII/MII physical interface support, and AXI4 Stream 32-bit packet data interface enable fast integration and confident design bring-up across a wide range of avionics process nodes and target applications.
