EMC Solution new


SEMCAD X Matterhorn EMC Solution harnesses the full power of FDTD to solve and accurately predict emission and EM compatibility (EMC) issues. Accurate emission and interference testing is extended beyond standard measurements, and time to market is significantly accelerated, to achieve a competitive edge.

Adaptive, rectilinear meshes can be generated interactively with excellent heuristics-based automatic grid generation and flexible tuning.

Drag-and-drop-based assignments are supported, and powerful interactive handling is featured (e.g., in geometric modeling, simulation coupling, and material assignment).

A novel pipeline architecture allows for the setup of complex analysis sequences and simple re-evaluations with modified input data or parameters. Analysis steps can be stored in and re-loaded from analysis or visualization “projects.”
