Latest Version of ANSYS Icemax Offers System-in-Package Support

    New Release Offers Key New Features to Simplify Design Flow of Next
    Generation 3-D Packaging Technologies

    SOUTHPOINTE, Pa., March 6 /CNW/ -- ANSYS, Inc. (Nasdaq:   ANSS), a global
innovator of simulation software and technologies designed to optimize product
development processes, today announced the release of version 3.0 of its
ANSYS(R) Icemax(R) software for circuit extraction of advanced integrated
circuit (IC) package designs. This new release provides IC package designers
with a flexible modeling environment, to set up and analyze a wide range of
system-in-package designs, including package-on-package, package-in-package
and package-on-PCB structures. ANSYS Icemax technologies are now part of the
ANSYS suite, from the company's 2006 acquisition of Fluent Inc. The release
aligns with the ANSYS focus on powerful industry solutions, based on the
Company's commitment to Simulation Driven Product Development.
    The ANSYS Icemax user interface allows users to import multiple designs
within the same model, use automatic alignment tools and analyze the assembled
design as a unified structure. "Stacked packages are becoming increasingly
common, especially in the handheld and wireless space. Existing design flows
in most semiconductor companies are set up to analyze individual layouts
separately and then connect them up in the system-level electrical model. For
3-D stacked packages, and in general system-in-package designs, this approach
has obvious limitations," says Chetan Desai, ANSYS Icemax product manager.
"The electrical model has to be extracted by accounting for all possible
interactions within the 3-D package assembly at the field solver level.
Appropriate return paths across package interfaces have to be accurately
detected for generating the final equivalent circuit. ANSYS Icemax 3.0
technology helps engineers realize this objective."
    The software enhancements are complemented by additional optimizations of
core meshing and field solver technologies that have been integral to earlier
product releases. Improvements have been made to simplify the specification
and detection of return paths in the package and PCB.
    Batch processing is a major new addition to the solver, providing further
automation in the design flow. ANSYS Icemax 3.0 software will continue to
operate on multi-CPU machines as well as 64-bit Windows(R) and Linux(R)
platforms, helping customers easily analyze high pin-count packages with
complex power and ground structures.
    New visualization capabilities include custom widgets for layer-by-layer
model display and finite volume mesh display.  Other key enhancements include
analysis of lossy dielectrics and specification of user-defined terminals in
the ANSYS Icemax model. In addition to RLCG data, results can now be exported
in the form of S/Y/Z parameters in industry standard touchstone format.
