10M/100M/1G/2.5G Ethernet TSN End Station Controller IP

Comprehensive hardware and software TSN capable solution 

The 10M/100M/1G/2.5G Ethernet TSN Endstation Controller IP is a comprehensive hardware and software solution for automotive, aerospace and industrial applications.  The solution implements Timing & Synchronization (802.1AS), Multiple types of Traffic Shaping (802.1Qav, 802.1Qby, 802.1Qcr), Frame preemption (802.1Qbu), Frame replication & elimination (802.1CB), Steam filtering & policing (802.1Qci), and optional MACsec encryption/decryption (802.1AE).

The solution is designed to provide high-precision time synchronization and accurate traffic scheduling. It supports up to 8 traffic classes, each with a dedicated queue for all ports. 

The 10M/100M/1G/2.5G Ethernet TSN Endstation Controller IP version is envisioned for demanding applications that demand high bandwidth, reliable and secure real-time communication and precision time synchronization.

 The IP supports 10M/100M/1G/2.5G operation and utilizes standard GMII/RGMII/SGMII and MDIO interfaces to communicate with Ethernet Physical layer devices. Its configuration and status register are accessible via a 32-bit AXI4-lite bus and include a multichannel high-performance DMA controller to transfer packets between the network interface and a host processor system. The DMA controller is connected to the host processor system via a memory-mapped AXI4 master port.

The 10M/100M/1G/2.5G Ethernet TSN Endstation controller IP includes a comprehensive software package with device drivers for several operating systems, a software stack for 802.1AS and a complete demonstration system based on Linux. The solution is available as technology-independent RTL source code (System Verilog) or encrypted netlist for ASIC and FPGA implementation. Furthermore, FPGA based hardware platforms are available for evaluation and prototyping.
