Next generation communications, networking, and consumer electronics products are replacing high-speed parallel interfaces with multi-gigabit serial links as the primary means of moving data within a system. Conventional signal integrity and timing analysis won’t work for these links, which require analyzing millions of bits worth of behavior to reliably determine how jitter, noise and crosstalk affect link operating margins. The IBIS-AMI modeling specification enables standardized, interoperable simulation of SerDes PHYs at the high levels of simulation performance and accuracy needed to correctly predict the behavior of serial links. This webinar highlights how IBIS-AMI based simulation will enable you to increase design reliability while reducing engineering design time.
Using SiSoft’s Quantum Channel Designer software and IBIS-AMI models, systems designers can experiment with different combinations of channel lengths, connectors, via designs and Transmit / Receive equalization to quickly determine which configurations provide adequate operating margin and which don't. Pre- and post-layout simulation with Quantum Channel Designer allows designers to validate designs and reduce time to market while increasing confidence in their design's reliability and manufacturability. This complimentary webinar will focus on the following topics:
* Xilinx IBIS-AMI simulation models for Virtex®-5, Virtex®-6 and Spartan®-6 * Predicting serial link operating margins using simulation * Co-optimizing your channel design and SerDes configuration * Assessing the impact of jitter, noise & crosstalk * Xilinx IBIS-AMI Design Kits for SiSoft’s Quantum Channel Designer

Official Windows 7 Support Timeline November 19, 2009
Dear Cadence Customer,
Cadence is planning to release the SPB and OrCAD ® 16.3 release in December 2009. It will initially support the following Windows Platforms:
• Windows 2003 Server, all Service Packs (32-bit only) • Windows XP Professional SP2&SP3 (32 Bit only) • Windows 2008 Server (32 and 64 Bit) • Windows Vista SP2 (32 and 64 bit) except Home Basic
We are currently in the process of validating our 16.3 code for use on Windows 7 (32 and 64 Bit) and anticipate completing this effort in March 2010. We have no plans to validate older SPB/OrCAD releases for Windows 7 support.
We thank you for your interest in using our tools on Windows 7 and look forward to fully supporting your needs.
Regards,
Rick Esposito SPB Operations Group Director Cadence Design Systems, Inc.
