Simulation Tools for Next-Generation Networks

Time Critical Networks AB (TCN) develops advanced simulation software for the design and evaluation of future-critical communication systems. Our flagship tool, TCN TimeAnalysis™, enables engineers to model and simulate digital twins of electrical architectures and networks — with a focus on Time-Sensitive Networking (TSN), the IEEE standards that bring determinism and timing reliability to traditional Ethernet.

By using simulation and digital twin technology, our users can accelerate their understanding of complex systems, test various “what-if” scenarios, and identify optimal configurations — all before any hardware is built.

Our Focus

TCN TimeAnalysis™ is primarily used in the automotive industry, helping engineers design robust, time-critical communication systems for autonomous driving — both in-vehicle and in external V2V/V2X environments.

Why Use TCN TimeAnalysis™?

• Maximize performance at minimum cost

  Quickly explore trade-offs across a wide design space to identify the best solutions.

• Gain deep insights

  Understand how traffic behaves across configurations — such as Ethernet backbones using AVB or TSN — and assess performance under various load scenarios.

• Ensure reliability

  Accurately predict best-, worst-, and average-case latency for each data stream, and ensure zero packet loss under real-time constraints.
