Call for papers

The Seventh Workshop on RTL and High Level Testing
November 23-24, 2006, Institute of System LSI Design Industry, Fukuoka, JAPAN
In conjunction with the 15th Asian Test Symposium (ATS'06) in Fukuoka

Sponsored by
IEEE Computer Society Test Technology Technical Council
Kyushu Institute of Technology
In cooperation with
Technical Group on Dependable Computing, IEICE

The purpose of this workshop is to bring researchers and practitioners of LSI testing from all over the
world together to exchange ideas and experiences in register transfer level (RTL) and high level testing.
WRTLT'06, the seventh workshop, will be held in conjunction with the 15th Asian Test Symposium
(ATS'06) in Fukuoka, Japan. We hope and expect this workshop provides an ideal forum for frank
discussion on this important topic for the future system-on-a-chip(SoC) devices.
Areas of interest include but are not limited to:
- Functional fault modeling
- Relationship between RTL and gate level testing
- High level approaches for testing
- SoC testing

Authors are invited to submit paper proposals for presentation at the workshop. The proposal may be
an extended summary (1,000 words) or a full paper and should include: title, full name and affiliation of
all authors, 50 words abstract, keywords and the name of contact author. All submissions should be
sent to the following address as Postscript or PDF attachment.

Submission deadline: July 28, 2006
Notification of acceptance: September 11, 2006
Camera ready due: October 9, 2006
Photocopies of accepted papers will be handed out
to the attendees at the workshop site.
