Electrical Simulation

 

Electrical simulation models the behavior of a high-speed electrical pulse traveling along a conductive path from its source to termination. Descriptive parameters include impedance, inductance, capacitance, and propagation delay. These are then integrated to generate S Parameter and Return Loss predictions versus frequency. These parameters, along with the interconnect SPICE model, may be incorporated into system simulations. Various signal-to-ground ratios are also modeled to predict cross-talk. Simulation software can visually depict the flight path of a traveling source wave relative to adjacent victim lines.

 

Variables that influence signal quality include connector geometry, materials selection and signal parameters. The ability to accurately define critical parameters and mesh these properties determines the quality of the simulation. Electrical simulation results are then linked to an iterative mechanical design model (prior to prototyping and/or production) thereby reducing cost and time to market.
