TSN Ethernet Switched Endpoint Controller

The TSN-SE implements a configurable controller meant to ease the implementation of endpoints for networks complying to the Time Sensitive Networking (TSN) standards. It integrates hardware stacks for timing synchronization (IEEE 802.1AS), traffic shaping (IEEE 802.1Qav and IEEE 802.1Qbv), frame-preemption (IEEE 802.1Qbu and IEEE 802.1Qbr), and a low-latency Ethernet MAC.

The controller core is designed to enable high-precision timing synchronization and flexible yet accurate traffic scheduling. With cut-through switching and minimal buffering even at the Ethernet MAC level, the TSN-SE features extremely low and deterministic ingress and egress latencies, and simplifies the development of time-aware applications. Furthermore, it allows the system to define and tune in real time the traffic shaping parameters according to an application’s requirements, and provides the system with timing information (time-stamps, alarms, etc.) that is typically required for the operation of a TSN network bridge or endpoint.

The TSN-SE uses standard AMBA® interfaces to ease integration. Its configuration and status registers are accessible via a 32-bit-wide APB bus, and packet data are input and output via AXI-Streaming interfaces with 32-bit data buses.


The TSN-SE is designed with industry best practices, and is available in synthesizable RTL (Verilog 2001) source code or as a targeted FPGA netlist. Deliverables provide everything required for a successful implementation, including sample scripts, an extensive testbench, and comprehensive documentation.
