Venice, Florida — Ansoft Corporation has released new versions of Nexxim®, the company's high-capacity circuit simulation software, and Ansoft Designer®, its
integrated schematic and design management software. The products include new statistical analysis and transient simulation capabilities that allow engineers to rapidly simulate high-speed serial channel behavior. This eliminates prototype iterations that require expensive test equipment and multiple spins that delay time-to-market.
Nexxim v4 features VerifEyeTM, a new methodology for eye analysis of serial links using statistical methods that maintain accuracy while offering major reductions in run time compared to conventional transient methods. These statistical transient analysis tools represent the most practicable means to test for the low bit
error rates needed by today's multi-Gb/s channel designers.
The new release also features QuickEyeTM, a new Ansoft-only fast eye
diagram analysis method that allows input of very long, user-defined bit streams. This analysis allows engineers to identify specific bit sequences that cause bit errors. The new technologies give engineers methods to rapidly predict system-level performance with eye diagram plots and bit error rates curves.
Additionally, Nexxim v4 features new mixed system-level behavioral simulation with transistor-level transient simulation. This hybrid integration enables designers to simulate a complete system consisting of various levels of abstraction much more quickly than in simulators that operate at only the transistor level.
Ansoft Designer v4 features a new "push excitation" feature and enhanced dynamic links to Nexxim and to Ansoft's electromagnetic field simulation tools. These products allow engineers to predict signal integrity effects and EMI/EMC performance of advanced
electronic systems, including gigabit communication channels, multi-function high-speed wireless systems and sophisticated microwave systems.
The products are currently available on PCs running Microsoft Windows XP Professional, Server 2003 and Vista Business. A release for the Linux and Solaris operating systems will follow shortly. For more information on product pricing and
