Abstract

We present the TrueTime Network library for Modelica; developed within the ITEA2 project EUROSYSLIB. It allows for simulation of various network protocols and is intended for use within real-time networking. We describe some its features and discuss implementational issues. Since TrueTime Network is programmed in C; special attention is given to the how Modelica’s external function interface is used. We also discuss briefly a future native Modelica implementation.
