Agilent Technologies Introduces Million-Bit-Per-Minute Channel Simulator for Signal Integrity


New Advanced Design System Simulator Speeds Eye Measurements for Multigigabit/s Chip-to-Chip Data Link Design

SANTA CLARA, Calif..- Agilent Technologies Inc. (NYSE: A) today introduced a million-bit-per-minute signal integrity Channel Simulator for multigigabit chip-to-chip data link design. The Channel Simulator -- part of Agilentís Advanced Design System (ADS) EDA software platform - allows an interactive eye measurement from channel simulations inside the ADS signal integrity design and analysis environment.

ďWith a throughput thatís a thousand times faster than SPICE, it is now practical to make changes to the channel or the transmit-and-receive equalization and see eye measurement results instantaneously,Ē said Colin Warwick, signal integrity product manager with Agilentís EEsof EDA division. ďThe Channel Simulator is unique because it allows our customers to build the model from regular ADS circuit- and physical-level components. They can access tuning, optimization and batch mode -- all from an intuitive user interface.Ē

The most common applications for the ADS Channel Simulator are design and verification of chip-to-chip multigigabit/s serial links. These are found in almost all consumer and enterprise digital products produced today -- from laptop computers to data center servers to telecommunication switching centers to Internet routers. At the very high data rates at which these links operate, signal-integrity engineers must take into account physical phenomena such as impedance mismatch, reflections, electromagnetic coupling, crosstalk and microwave frequency attenuation due to the skin effect and dielectric loss tangent.

The ADS Channel Simulator allows signal integrity engineers to address these challenges by performing ďwhat-ifĒ design space exploration. To aid this workflow, ADS Channel Simulator uses impulse response analysis to automatically extract a fast, linear FIR model from any combination of ADS circuit-level and physical-level components. This results in simulation throughputs of more than a million bits per minute. Fast eye measurement lets signal-integrity engineers interactively produce the resulting eye measurements -- and optimize transmit and receive equalization -- in serial links such as PCI Express(r), USB 3.0 and 10-gigabit Ethernet.

Agilentís Advanced Design System is a powerful electronic design automation platform. It offers complete integration to designers of multigigabit/s serial links; consumer and commercial wireless electronic products, such as mobile phones, wireless networking and GPS; and radar and satellite communications systems.

U.S. Pricing and Availability

Agilentís Channel Simulator will be available as part of the Advanced Design System 2009 release, available in mid-February. The Channel Simulator is offered as part of both the legacy E8885 Convolution Simulator and its successor, the new W2302 Transient Convolution Element in Agilentís Advanced Design System. Prices start at approximately $26,000.
