Abstract
Examples of the invention include methods and apparatus for determining an electromagnetic field, such as a magnetic field, at a selected location within computer-aided design (CAD) data. An example approach may include selecting a location by clicking on, or otherwise selecting the location within a visual representation of the CAD data, selecting one or more electrical components within the CAD data, retrieving electrical current data and distance data for each of the selected electrical components, and determining the electromagnetic field at the selected location using electromagnetic theory. Examples of the invention allow rapid determination of potential electromagnetic noise problems in the CAD design stage, before prototyping and without the complexity of a full 3D electromagnetic simulation.
