Ensuring Accurate Broadband EM Analysis with Allegro PCB Designer

This application note outlines the electromagnetic (EM) simulation and verification flow between the Cadence Allegro PCB Designer and Cadence AWR Design Environment platform, specifically AWR Microwave Office circuit design software and the AWR AXIEM EM simulator for a PCB design. The example uses a simple transmission line with known response to validate the approach and demonstrate interoperability between design and analysis tools. Following the export/import steps, the creation of an EM simulation structure is shown and the trade-offs between design complexity and simulation time are discussed. Lastly, an introduction to basic EM port configuration and simulation settings is provided and a comparison of the AWR AXIEM EM simulation against measured results is shown.
