ANSYS Releases SIwave 4.0

Unparalleled Advancements in Signal- and Power-Integrity, Electromagnetic
Compatibility Testing
SOUTHPOINTE, Pa.--(Business Wire)--
ANSYS, Inc. (NASDAQ: ANSS), a global innovator of simulation software and
technologies designed to optimize product development processes, today announced
the latest release of SIwave software. Part of the Ansoft family of products,
version 4.0 of this technology includes new features for signal-integrity,
power-integrity and electromagnetic compatibility testing. It includes numerous
enhancements including an improved desktop graphical user interface with new
post-processing of results, solver enhancements that provide accurate solutions
beyond 10 Gb/s, and automation that links SIwave electromagnetics with circuit
simulation using Ansoft Designer® and Nexxim®. Additionally, a new link between
electromagnetics and thermal analysis has been created for board and package
thermal effects via ANSYS® Icepak® software. The link enables accurate
characterization of additional heating due to copper-resistive losses that
engineers have previously estimated or ignored completely.

SIwave technology is an electromagnetic field solver that performs broadband
signal- and power-integrity analyses along with DC voltage and current analysis
for complete boards and packages. SIwave software offers comprehensive
electromagnetic interference and compatibility analyses, and it has the unique
ability to couple board and package electromagnetic fields with HFSS technology
for complete system-level simulation.

"SIwave 4.0 will allow designers to continually push the envelope of high-speed
design, deliver first-in-class performance, and go beyond the 10 Gb/s design
barrier that exists in high-performance computing," said Dr. Zol Cendes, chief
technology officer and general manager at Ansoft. "These advancements in
electrical simulation plus the coupling between SIwave and ANSYS Icepak provide
a comprehensive solution for our customers."

SIwave features an enhanced graphical user interface that makes component
management easy and allows simultaneous analyses and dynamic zooming. A new
reporter feature makes the analysis of results easy and fast. Improved solver
enhancements include smart coupling algorithms with an advanced via solver
combined with non-uniform (hexagonal and trapezoidal) trace cross-sections that
provide accurate solutions beyond 10 Gb/s. A new co-planar algorithm within the
solver extends accuracy for difficult package designs, and a new field solver
calculates trace characteristics on the fly. Enhanced near- and far-field
solvers provide an unmatched solution to electromagnetic interference and
compatibility problems for data-dependent fields when linked to circuit
simulation using Ansoft Designer® software.

The latest release includes multiple automation enhancements that ease design
flows by removing tedious manipulations that, most often, are done manually.
Automated error checking and geometry correction have been implemented within
SIwave software. Schematic creation, transient and QuickEye analyses setups have
been automated for circuit simulation driven by electromagnetics when using
SIwave with Ansoft Designer. The technology now also allows native merging of
packages to boards. SIwave also allows automated port creation for Apache
RedHawk chip power modules based on the provided header information.

"Version 4.0 of SIwave has added significant improvement to our design
capabilities, making it an invaluable analysis tool for signal and power
integrity applications. It's a significant step toward the goals of first-pass
system success and reduction of the number of fab spins (design iterations),"
said George Peterson, lead signal integrity engineer at Jabil Technology
