High performances TSN IP cores by Safe Connect Systems

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

By the way TSN has been introduced to address efficiently deterministic applications in various fields of industry. Inside this wide deterministic applications area, we assume that two main segments of use can be identified due to safety requirements as described in the next table.

The first segment (in green) covers deterministic applications with low criticality level. They are mostly located in the factory automation world and when onboarded in vehicles for non-vital applications.

The second segment (in blue) covers deterministic application with high criticality level. They are mostly related to vehicles vital applications and also in factory automation for very high productive and reliable uses.

In that context Safe Connect Systems has been developing a library of TSN IP Core to allow end users to design complete ad hoc solutions for their TSN critical applications. Starting from this library we have designed 3 main COTS IP Core that are sufficient for developing first powerful applications in the TSN field:

For more experienced users, SCS provides its complete library of elementary IP- Cores that allow to design ad hoc compositions. Please contact us to know more about the complete library.

 

Undisputed advantages of TSN technology by SCS

Safe Connect Systems (SCS) IP Cores allow to design full deterministic TSN critical applications with a full range of undisputed assets.


TSN stack full hardware powerful implementation that reaches undisputed Performances such as Node synchronization accuracy, Switch traversal time, Ultra-Low Latency and Effective Bandwidth allocation.

This implementation simplifies End User system design and reduces drastically development and recurring costs:
o Very Easy, flexible and reliable Hardware interfacing
o Very easy application integration
o Functionally Extensible with end user HDL application code
o Entirely Customizable: ports, memory, routing table
o Strong level of integration with smart sensors or actuators

This implementation of the TSN Stack is fully deterministic
o Supports any TSN scheduler
o Provides deterministic best (BCCT) and worst (WCCT) case communication time
o Provides a very short time gap between BCCT and WCCT
o Makes simple the demonstration of qualification for safety critical applications

Considering its very small Footprint so that the IP Core can be onboarded on a large range of chips.

Several internal powerful mechanisms for maximum security against intrusion.

A set of additional value-added services over TSN that are simply accessible for the end user in order to reduce drastically the development of critical applications. These services reduce also drastically the recurring cost by minimizing the additional hardware required to monitor the critical system.
