Asynchronous circuits have potential advantages
of higher speed and lower power consumption compared to
their synchronous counterparts, but their poor CAD support
is a major issue limiting adoption. In this paper, we present
an integrated timing and power analysis engine capable of
handling large asynchronous circuits. For timing, we introduce
the notion of performance and correctness slack for asynchronous
circuits; for power, we compute both the static and
dynamic components. We provide a hierarchical approach to
constructing the event-dependency graph, and use the Galois
framework for parallelization to achieve fast runtime. The net
result is Cyclone, a fast and accurate engine for both static
timing and power analysis of asynchronous circuits
