INTRODUCTION
Modern telecommunication systems are highly complex from an
algorithmic point of view. The complexity continues to increase due to
advanced modulation schemes, multiple protocols and standards, as well as
additional functionality such as color displays, personal organizers,
navigation aids, cameras, and audio-visual support.
At the same time both silicon area which means costs and power
consumption of the devices have to be reduced and the design time
shortened. This is inevitable to keep profitability in this fast evolving high
volume consumer market.
These conflictive demands force the need for efficient design and
verification methods. To have short and reliable design cycles, verification is
necessary very early in the design process. Modeling and simulation need to
accompany the design steps from the specification to the overall system
verification in order to bridge the gaps between system specification, system
simulation, and circuit level simulation. Therefore this book contains
application-oriented training material for RF designers which combines the
presentation of a mixed-signal design flow, an introduction into the
standardized powerful hardware description language VHDL-AMS, and the
application of commercially available simulators. The focus lies on RF
specific modeling and simulation methods and the consideration of system
and circuit level descriptions.
An early version of some parts of this book, especially some of the
VHDL-AMS models, has been tested in a Nokia-internal course with about
50 designers. In this course a web-based education and simulation
environment has been used, developed in a European research project LIMA
(Learning Platform in Microelectronics Applications).
