SPICEnetwerkanalyses

SPICEnetwerkanalyses is a methodological framework that integrates SPICE-based circuit simulation with graph- and network-theoretic analysis to study systems that can be modeled as electrical networks. The core idea is to represent a network as a netlist of nodes, components, and their interconnections, then use SPICE to simulate electrical behavior while applying network metrics and analyses to interpret the results. This combination supports understanding both local device behavior and global network dynamics.

In practice, a SPICEnetwerkanalyses workflow begins with constructing a circuit-like representation of the target network from topology data. DC operating points, transient responses, AC small-signal analyses, and noise analyses are performed with SPICE to obtain voltages, currents, impedances, delays, and stability information. Parametric sweeps, Monte Carlo simulations, and sensitivity analyses are often used to account for component tolerances and uncertainties. Results from SPICE are then mapped onto network-level descriptors such as propagation delay, signal integrity margins, impedance matching, and energy dissipation.

Key aspects of the approach include device-level modeling, where nonlinear elements (diodes, transistors) influence network dynamics, and topology-level analysis, where graph measures (centrality, path lengths, clustering) aid interpretation of failures, bottlenecks, and robustness. The framework also supports optimization and design refinement, linking electrical performance with network resilience objectives.

Applications span power distribution and smart-grid segments, high-speed interconnects in electronic systems, RF and microwave networks, and reliability studies involving cascading failures. Limitations involve scaling to very large networks, calibration of device models with real-world data, and the trade-off between detailed SPICE accuracy and high-level network insight.
