PowerSI

Easily model complex structures including cuts and slots in planes, multiple power and ground layers, vias, and traces with auto-adaptive numerical meshing using the fast, accurate, 2.5D solver in PowerSI. Visualize complex spatial relationships and achieve realistic system-level simulation by extracting the unique parasitics and interconnects of the design with S-Parameter modeling.

Unlike traditional SI tools that treat power and ground planes as ideal with fixed voltages, PowerSI considers all signal and plane effects simultaneously. Accurately analyze coupling, impedance, references, simultaneous switching noise, and more to improve signal quality.

PowerSI anticipates energy leaks with near-field and far-field radiation display to reduce downstream electromagnetic interference (EMI)/electromagnetic capability (EMC) challenges. Easily identify problematic EMI radiating devices and the extent of noise to determine necessary shielding and faraday cage placement.

Evaluate the current/voltage induced on the PCB or package through an external plane wave source to accurately determine the impact of external radiation and overall system susceptibility.

Identify resonant modes between predefined frequency ranges and analyze cavity resonance of the Power Delivery System to prevent electrical spikes.

PowerSI helps you to determine the effects of external power delivery, conducted emissions, and coupling paths to reduce noise on the Power Delivery Network.
