The research of our group focuses on many aspects of asynchronous (and synchronous) digital design.  Asynchronous, or self-timed, circuits are those which do not use a global clock.  Recent research topics include: CAD tools and algorithms; the design of high-performance and low-power datapaths; controller-design; high-speed pipelines; design of interface circuits for mixed-clock and mixed asynchronous/synchronous systems; logic synthesis; and formal hardware verification.
