چکیده
added value of the methodology in terms of area, power, speed, electromagnetic interference (EMI), noise immunity, and so on; tradeoffs, which design parameters often worsen to achieve added values, such as speed versus power, and area versus EMI; and the cost of switching to the new methodology, including training time, development of new libraries, and time spent dealing with CAD tool immaturity.

0740-7475/02/$17.00 © 2002 IEEE July–August 2002 EDA FLOWS are industry driven, and thus use synchronous methodologies as de facto standards. However, implementation problems arise from imposing a synchronous model of operation on deep-submicron circuits. This problem motivates the investigation of other, asynchronous modes of operation. Acceptance of new design methodologies, including asynchr...

| A comparison with synchronous circuits suggests four opportunities for the application of asynchronous circuits: high performance, low power, improved noise and EMC properties, and a natural match with heterogeneous system timing. In this overview article each opportunity is reviewed in some detail, illustrated by examples, compared with synchronous alternatives, and accompanied by numerous p...
متن کاملRelative Placement in Timed Asynchronous Design
Timed asynchronous circuits can be implemented using commercial computer-aided design (CAD) tools. Relative timing methodology is applied for interpreting the complex timing of asynchronous circuits into CAD tools that can be understood with minimum and maximum timing constraints. Typical synchronous placement algorithm neglect timing information which is critical for asynchronous methodology. ...

متن کاملAutomatic synthesis of extended burst-mode circuits. I.(Specification and hazard-free implementations)
We introduce a new design style called extended burst-mode. The extended burst-mode design style covers a wide spectrum of sequential circuits ranging from delay-insensitive to synchronous. We can synthesize multiple-input change asynchronous finite state machines, and many circuits that fall in the gray area (hard to classify as synchronous or asynchronous) which are difficult or impossible to...
