CheckT/sub c/ and minT/sub c/: timing verification and optimal clocking of synchronous digital circuits
Karem A. Sakallah, Trevor Mudge, Kunle Olukotun · 2002
Two CAD tools, checkT/sub c/ and minT/sub c/, for timing verification and optimal clocking are introduced. Both tools are based on a new timing model of synchronous digital circuits. The model has the following features: (1) it is general enough to handle arbitrary multiphase clocking; (2) complete, in the sense that it captures signal propagation along short as well as long paths in the logic; (3) extensible to make it relatively easy to incorporate 'complex' latching structures; and (4) notationally simple to make it amenable to analytic treatment in some important special cases. These tools are being used to help in the design of a 4 ns gallium arsenide micro-supercomputer.>
