Architecture and CAD for Deep-Submicron FPGAs

Betz, Rose & Marquardt

Since their introduction in 1984, Field-Programmable Gate Arrays
(FPGAs) have become one of the most popular implementation media for
digital circuits and have grown into a $2 billion per year industry.
As process geometries have shrunk into the deep-submicron region, the
logic capacity of FPGAs has greatly increased, making FPGAs a viable
implementation alternative for larger and larger designs. To make the
best use of these new deep-submicron processes, one must re-architect
one's FPGAs and Computer-Aided Design (CAD) tools.

Architecture and CAD for Deep-Submicron FPGAs addresses several key
issues in the design or high-performance FPGA architectures and CAD
tools, with particular emphasis on issues that are important for FPGAs
implemented in deep-submicron processes.

Three factors combine to determine the performance of an FPGA: the
quality of the CAD tools used to map circuits into the FPGA, the
quality of the FPGA architecture, and the electrical (i.e.
transistor-level) design of the FPGA. Architecture and CAD for
Deep-Submicron FPGAs examines all three of these issues in concert.

In order to investigate the quality of different FPGA architectures,
one needs CAD tools capable of automatically implementing circuits in
each FPGA architecture of interest. Once a circuit has been
implemented in an FPGA architecture, one next needs accurate area and
delay models to evaluate the quality (speed achieved, area required)
of the circuit implementation in the FPGA architecture under test.
This book therefore has three major foci: the development of a
high-quality and highly flexible CAD infrastructure, the creation of
accurate area and delay models for FPGAs, and the study of several
important FPGA architectural issues.

Architecture and CAD for Deep-Submicron FPGAs is an essential
reference for researchers, professionals and students interested in
