Digital Twin Modelling of Networks and Electrical Architectures

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.
