When to Use Sonnet EM Analysis

The use of electromagnetic analysis with Sonnet Professional is especially valuable in the

following design situations:

When parasitic coupling is present. Parasitic coupling is not always easy to predict

without using electromagnetic analysis. Even elements which are "sufficiently" far apart

can suffer from parasitic coupling: inductive or capacitive coupling, resonance effects due

to grounding and surface waves that might propagate at the substrate boundary under

certain conditions. Sonnet Professional analysis is based on the physical properties of your

technology and will account for such physical effects.

When accurate circuit models are not available or circuit model parameters are out

of range. Model based circuit simulators are based on models for a specific application,

with limited parameter range. For example, only selected geometries, substrate types and

substrate parameters are available. It is difficult to estimate the error induced by

parameter extrapolation, so using models outside their designed parameter range is not

suitable for critical applications.

Whenever a layout feature cannot be described by a circuit model, due to its geometry or

technology, the physics based analysis with Sonnet Professional will provide the answer.

An example for this could be a special inductor, capacitor or transformer which is not

included in the design kit. Sonnet can be used to analyze those components "on the fly", or

generate a full library of components models with trust worth electrical results.
