Signal- & Power-Integrity Analysis

ANSYS SIwave employs specialized full-wave finite element algorithms to compute resonances, reflections, intertrace coupling, simultaneous switching noise, power/ground bounce, DC voltage/current distributions, near- and far-field radiation patterns on high-speed PCBs and complex IC packages.

Integrated and Automated DC I²R Reporting  

An integrated I²R computation module allows you to perform pre- and post-layout DC voltage drop, DC current density and DC power density analyses. This will ensure that power distribution networks (PDNs) can source the proper power to integrated circuits by checking that the PDN has the proper bump, ball and pin sizes as well as proper copper weighting to minimize losses. Additionally, all this crucial information is automatically generated with a single button click.
