Advanced Design System 2011 Momentum solves power integrity problems complicated by heavily perforated power and ground planes. Contains full wave 3-D multilayer electromagnetic field solver that yields power distribution network impedance for an arbitrary input mixture of power, ground and signal nets on each layer. Results said to be valid into the multi-gigahertz range. Can be applied to heavily perforated printed circuit boards and high-frequency IC package power integrity problems. Includes a signal integrity/power integrity analyzer that provides a simple net-based electromagnetic simulation setup wizard and automatic test-bench generator for typical SI/PI circuit simulations. Models wire bonds, the effects of frequency-dependent dielectric loss and the surface roughness of copper traces.
