Agilent Technologies Introduces Power Integrity Solution to Solve Key Challenge in Designing Power Distribution
SANTA CLARA, Calif., Feb. 1, 2011 – Agilent Technologies Inc. (NYSE:A) today introduced its
power integrity solution
to quickly and accurately solve the perforated-plane power integrity challenge. Available in Agilent’s
Advanced Design System 2011 Momentum, the
solution is used for designing a power distribution network with the heavily perforated power and ground planes
found in modern printed circuit board designs.
Traditionally, boards have had dedicated power and ground
planes that were independent from the signal planes. Because the power and ground planes were used exclusively for
that purpose, they were practically continuous sheets with few, if any, perforations. The previous generation of
power integrity electronic design automation tools relied on this topology by using approximations that increased
simulation speed but were valid only in the case of solid power and ground planes.
The demand for
high-volume, cost-reduced boards has been met with a new design paradigm called split-power ground layout where
signal lines cohabit and perforate the power and ground planes. This approach dramatically reduces the layer count
and cost of the board, but renders useless previous generation power integrity tools.
The power integrity
solution in Agilent’s ADS 2011 Momentum solves power integrity problems that are complicated by heavily perforated
power and ground planes. Unlike other power integrity tools, Momentum does not assume solid power and ground
planes. It contains a 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. Unlike previous
generation static and pseudo-static power integrity solvers (which are accurate only up to several hundred
megahertz), the results from Momentum are valid into the multi-gigahertz range This enables the tool to be applied
to heavily perforated boards, as well as high-frequency IC package power integrity problems.
R&D team created this capability by enhancing the speed and capacity of the proven method-of-moment technology in
Momentum. The enhancements allow Momentum to be applied to very large structures such as power distribution
Traditionally, Momentum has been used for smaller RF and microwave structures where a
polygon-based layout design and setup is preferred. Power integrity engineers, however, prefer to import the
artwork from an enterprise board tool and then apply a net-based setup where port-to-port connections, not raw
polygonal shape data, determine the electromagnetic simulation setup. For this reason, ADS 2011 now 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.
In addition, Momentum also now models wire bonds, the effects of frequency-dependent dielectric loss and the
surface roughness of copper traces, which are important in signal integrity and power integrity design.
