Physical Layer Simulation of Large Distributed Automation Systems in SPICE.
SIMUL 2013 - The Fifth International Conference on Advances in System Simulation, Venice, Italy, October 2013.


In this paper, we propose an analysis of the physical layer of large distributed automation systems based on simulation in SPICE. For large systems, changes of the physical topology or minor modifications of the physical layer hardware of a bus node result in much more increased influences to the signal integrity compared to smaller system architectures. The simulation provides references for further designs of the physical layer hardware of a bus node and an analysis of its behavior in different large topology configurations with up to 1000 bus nodes in a network with a total length of up to 1000 meters.
