Simulation tools for evaluating next generation networks

Network digital twins and simulation offer efficient means for getting through learning curves faster, analyzing different what-if scenarios and finding optimal configuration settings.

Time Critical Networks AB (TCN) develops TCN Time Analysis™ for digital twin modelling and simulation of primarily automotive electrical architectures and networks that incorporate Time-Sensitive Networking (TSN), the new IEEE standards for making traditional Ethernet networks more deterministic and robust with regards to time-sensitive data streams.

Early users of the tool are found within the automotive industry, using the software for designing the upcoming autonomous driving communication systems, in-vehicle as well as outside the vehicle (V2V/V2X).

Benefits of using TCN Time Analysis™ include:

  • Maximize performance at minimum cost - Quickly examine trade-offs in a large design space
  • Gain insights - Understand how the traffic behaves under different network configurations and usage scenarios, e.g. in an Ethernet backbone with AVB or TSN functionality
  • Ensure Ethernet can be used - Identify best, worst- and average case latency for individual data flows forwarded and ensure no loss of packets.
