System Simulation Software
A new version of the LINC2 VSA (Visual System Architect) system simulation software has recently been released by ACS. Version 1.03 adds new system components and behavioral models to the VSA's Components menu. A new bandpass filter model with ideal selectivity is now part of the list of available components. The Visual System Architect offers the flexibility and ease of use of schematic-based system simulation combined with a comprehensive array of analysis methods and graphic displays for designing at the system level. More information about the Visual System Architect and other LINC2 products from ACS can be found on the ACS web site.

iFilter Software
AWR Corp. announced its new iFilter technology, which was developed specifically for synthesis of lumped-element and distributed filters. iFilter's intuitive user interface enables users to quickly and easily design filters, connect them directly to circuitry, and make optimization trade-offs that positively impact their designs. It operates seamlessly within AWR's Microwave Office® high-frequency design software, allowing filter designs and their evolution to be part of the entire circuit design project. iFilter's physical layouts are automatically generated for distributed filters, while lumped-element filters can be realized using an extensive library of manufacturers' components (inductors, capacitors, etc.).

Multiphysics Simulation Software
COMSOL Inc. announces that version 4.0 of its multiphysics simulation software is now shipping. First unveiled at the 2009 users conference in Boston, COMSOL Multiphysics version 4.0 features an all-new user interface that makes the power of multiphysics simulation available to a wider audience of scientists and engineers. Both expert analysts and non-experts alike will benefit from the organized layout and streamlined model-building process. Along with the release of version 4.0, COMSOL also announces the release of a series of new LiveLink™ options that tightly integrate COMSOL Multiphysics into the mainstream product design workflow. New LiveLink products are now shipping for Autodesk® Inventor®, Pro/ENGINEER®, SolidWorks® and MATLAB®.

EM Simulation
Version 5.40 of EMPIRE XCcel™ software enables one simulation job to be distributed on multiple, networked PCs. This almost infinite extension of memory-space, based on the resources of the PC-network available, increases the complexity of tasks the software can tackle, i.e. higher resolutions and/or larger dimensions. Other features of version 5.40 include: the completely automated distribution of files and data throughout the simulation run, easy configuration capability for multiple hosts, transparent job-management by visualization of configuration and processes, and performance and simulation-speed is scaled linearly with the number of PCs.

Filter Topology Solution
As a new feature in its flagship product, Filter Solutions®, Nuhertz Technologies® has introduced a solution for the synthesis of "Multiple-Band™" filter networks. The term describes the construction of a cascade of an arbitrary number of pass and stop bands in a single lumped LC, active, or digital IIR filter. This robust feature adds to the power of the versatile and unique filter solutions. The "Multiple-Band" solution solves the design problem for "N-band" filters wherein ìNî is an arbitrary integer. In network designs wherein cascades of individual passive filters are needed, the individual filters will necessarily interact, thus altering the desired network response. Such design problems are common in multiple passband VDSL or other filters used in data communications over telephone lines. The design solution synthesizes the geometric asymmetries in the various required pass and stop bands.
