Project Title
CAREER: A Comprehensive High-Level Design Validation Approach for
Microprocessors
Project Summary
This project concentrates on a career development plan for
integrating research and teaching in the field of design validation. The
research component focuses on devising practical methods for high-level design
validation of microprocessors and supporting CAD tools based on explicit design
error modeling, design error simulation, model-directed test generation, and
design error correction. Specifically, the research concentrates on the
following issues: (a) the development of a high-level design error simulation
method based on a new high-level critical path tracing approach; (b) the
establishment of high-level controllability and observability measures that can
be used to guide the test generation for design errors; (c) the development of
high-level test generation algorithm(s) that generate instructions to detect
modeled and actual high-level design errors in microprocessors; (d) the
development of high-level design error location, diagnosis, and correction
methods that pinpoint the error location and suggest ways to correct it; and (e)
the formation of a set of guidelines that facilitate design for validation and
post-silicon validation. The teaching component concentrates on enhancing the
undergraduate and graduate programs in our department by introducing new
graduate and undergraduate courses on design verification and incorporating
current research results into them, active mentoring of undergraduate students,
effective supervision of research for graduate and undergraduate students,
active collaboration with the computer industry, and outreach activities to
freshmen students as well as undergraduate students at the national level.
