Klappentext
This book is devoted to logic synthesis and design techniques for asynchronous circuits. It uses the mathematical theory of Petri Nets and asynchronous automata to develop practical algorithms implemented in a public domain CAD tool. Asynchronous circuits have so far been designed mostly by hand, and are thus much less common than their synchronous counterparts, which have enjoyed a high level of design automation since the mid-1970s. Asynchronous circuits, on the other hand, can be very useful to tackle clock distribution, modularity, power dissipation and electro-magnetic interference in digital integrated circuits. This book provides the foundation needed for CAD-assisted design of such circuits, and can also be used as the basis for a graduate course on logic design.
