> FPGA and EDA: Working Together
> *****November 20, 2003 11 AM PST*****
> As FPGAs grow in complexity, designers must overcome
> the same challenges presented by high-end ASICs,
> including achieving performance requirements, long
> verification time, integration of IP, multi-cycle clock
> domains, and high speed board design signal integrity
> issues. Technologies developed for high-end ASICs -
> such as assertion-based verification, physical
> synthesis, silicon virtual prototyping, power analysis,
> and others - must now be made available for FPGAs. How
> is the EDA industry stepping up to deliver the same
> quality FPGA tools that have made so many ASIC
> designers around the world successful? Join Brian
> Fuller, editor-in-chief of EE Times, and a panel of
> industry experts in an on-line discussion about what
> it's going to take to do a complex FPGA design and how
> the industry is ready to reach these goals.

> Dialog Semiconductor
> Power management in cell phones
> *****December 4, 2003; 11 am PST*****
> Each year, the pocket cellphone includes more features
> and functions. No longer just a palm-sized PDA and
> address book, the modern cellular telephone is also an
> MP3 audio player, a digital still camera, a video
> streaming media display - even a gaming platform. But
> each new feature extracts a price in terms of power
> consumption. How the modern cellphone gets more than 15
> minutes of battery life is one of the great mysteries
> of analog design. In this editorial NetSeminar, veteran
> EE Times editor Stephan Ohr and panel of technologists
> from Linear Technology, National Semiconductor, Texas
> Instruments and Dialog Semiconductor (the seminar's
> sponsor) will explore the design issues associated with
> cellphone power management. The panel will review
> voltage regulator topologies that promote low noise and
> efficiency, describe the microprocessor handles that
> enable power-saving sleep modes; and discuss
> semiconductor integration techniques and processes that
> enable power conservation in handheld devices.

> When Analog and Digital Co-exist on One Chip: Advanced
> Data Conversion Architectures
> *****December 11, 2003 11 AM PST*****
> Data conversion technology is a vital element in a wide
> variety of new-generation applications ranging from
> communications to consumer goods. Data converters must
> constantly evolve to meet stringent new system and
> market demands for higher accuracy and speeds, and
> lower-power and cost. In many modern systems, data
> converters are one of the key signal processing
> elements and are relied-upon to enable next-generation
> system performance and features. But how will these
> intricate mixed-signal devices meet the needs of the
> digital future? In this challenging and instructive EE
> Times Editorial NetSeminar, a panel of key
> technologists will share their insights on future
> trends in data conversion technology, the evolution of
> converter architectures, and the prospects of
> upstream/downstream signal chain integration. Stephan
> Ohr, Analog/DSP CMP Electronics Group Editorial
> Director, will moderate this enlightening discussion to
> explore the state-of-the-art in data converters today
> and provide a unique view of the roadmap to their
> future.
