PATMOS'96
Sixth International Workshop Program
Bologna, Italy
23 - 25 September 1996
The PATMOS Workshop
The workshop is the sixth of a series of international workshops held in
Kaiserslautern, Germany, 1991, Paris, France, 1992, Montpellier, France,
1993, Barcelona, Spain, 1994 and Oldenburg, Germany, 1995. It originated from technical meetings of
the European project Power And Timing Modeling Optimization and
Simulation. PATMOS has over the years evolved into a well established and
outstanding series of open European events on power and timing at the
logical and physical level of design. Within this scope, design issues and
CAD related topics are covered. The availability of deep sub-micron
technology has recently increased interest especially in low-power design
and this gives additional momentum to the interest in this workshop.
This development has also extended the scope of PATMOS to higher levels of
abstraction, in particular for power optimization. Despite its growth, the
workshop can still be considered as an informal, but very focused conference,
featuring high level scientific presentations, together with open discussions
and panel sessions, in a free and easy environment. This special atmosphere
has proven to be an excellent origin of new ideas and interesting
co-operations and projects.
This year program
The technical program for PATMOS 96 has the same general structure as
last editions', to consolidate a satisfactory tradition, but, also
simply because it has been proven to be adequate and successful.
The technical sessions are devoted to the most important and
up-to-date subjects concerning IC design and characterization,
with particular emphasys on power consumptions and signal delays,
traditional to the workshop, but to interesting
related subjects, such as IDDQ testing and non-conventional architectures.
The technical sessions will be accompanied by three invited papers,
given by particularly qualified speakers, concerning tools and
enviroment for power estimation and synthesis, simulation for reliability
and on chip IDDQ testing.
Finally, in the best workshop tradition, a panel of competent expert
will discuss design tools at RTL level from the point of expectations
and actual performance.
Naturally, plentiful discussions among the participants are an
integral part of the program.
A concert, a banquet and the charming enviroment of Bologna
will certainly help in making the workshop more enjoyable.
The Department of Electronics, Informatics and Systems (DEIS) represents
one of the largest scientific institutions of the University of Bologna,
the oldest in the world.
DEIS has about 150 members, including Professors, Research Assistants,
Technicians, Staff Members, Ph.D. Students,..., whose activity covers a
very wide and diversified
ground, including all modern Information Technologies.
Scientifically, it has a strong reputation at international level in
several fields. Furthermore, it makes a significant effort to
teaching, as well as in continuing education of engineers and
technicians employed in industry.
Collaboration with large and small enterprises, in Italy as well as
abroad, is a common practice in the activity of DEIS.

About Bologna
Capital city of Emilia-Romagna, Bologna is at the intersection
between northern and central Italy. Its population is half a milion. Originally
an Etruscan settlement, it fell under Gaulish rule in 400 B.C. to eventually
become a Roman colony. About 1088 A.D. the oldest university in the world
was founded within its walls. Historic mansions and churches line the
streets of one of the best preserved old towns in Europe, and highlight
its cultural heritage through the ages. A typical landmark of the town
is the line of porticoes adorning the streets, stretching to almost 40
kilometers.
How to reach Bologna
By car: the main highway connection
is A1, "Autostrada del Sole", that joins Bologna to Milan,
Florence and Rome and links it to other three guiding highway: Turin-Brescia
A21, Genoa-LaSpezia A15, Brennero-Verona A22. All the highway exits to
Bologna get into a ring road (Tangenziale), from which
all directions can be easily reached.
By train: Bologna is the main Italian railway
junction, therefore all the most important national and international
lines touch it.From the railway station bus and taxi services
are available. The bus ticket can be purchased at Tabacco Shops or Newspaper
Stands, and costs Lit. 1500. The Railway Station is close to the town-center,
so the hotels chosen for the workshop can be reached in few minutes' walk.
By plane:
flights from abroad arrive at Guglielmo Marconi Airport, convenientely
located near the city, with easy bus and taxi connection. A taxi costs
approximately Lit. 25000 - 30000.
Bus n. 91 - Starting at 6,10 am.
leaves every hour from the Airport and stops in the centre of the City and the Railway station.
A special bus called Aerobus starts at 6,40 am. and also brings to downtown.
Its frequency is every 30 min. The ticket can be purchased on the bus
and costs Lit. 6000.
