Deterministic Ethernet solutions, like TSN, deliver streams with guaranteed bandwidth and deterministic latency. 

Time Sensitive Networking (TSN) is the name of the IEEE 802.1 Task Group responsible for standards at Data Link Layer. This group provides the specifications that will allow time-synchronized and low latency streaming services through IEEE 802 networks.

TSN is evolving and it is targeting different sectors, like Automotive, Industry, Broadcasting and Aerospace. Therefore, it is expected switching implementations that combine a subset of the available standards and features. This flexibility can be achieved through reconfigurable logic (FPGAs), HDL IPs and embedded software.

Multiport Time Sensitive Networking (MTSN) Switch IP core is a flexible HDL code ready to generate TSN end-point or bridge implementations. The IP has been provided with a rich set of Generic parameters to obtain the best functionalities resources trade-off. These generic can be configured at VHDL level or graphically thanks to the GUI interface provided for Vivado IPI. 

MTSN is supported on the following Xilinx FPGA Families:

  • 7-Series (Zynq, Spartan, Artix, Kintex, Virtex)
  • Ultrascale (Kintex, Virtex)
  • Ultrascale+ (Zynq MPSoC, Kintex, Virtex)
