Asynchronous logic may be used simply for the interfacing of a synchronous system to its environment and other synchronous. Typical problems will be the design of ip-ops arbitraters synchronous switches and a variety of other sequential circuit blocks which are used in com-plex digital systems. Asynchronous logic design.
Asynchronous Logic Design, In a Synchronous Sequential Circuit all the State Variables representing the internal state of the circuit change their state simulteneously with a given input clock signal to achieve the next state. After two decades during which clocked logic has imposed its discipline across all corners of the world of digital logic the older and more anarchic approach seems poised to make a come-back. Asynchronous logic may be used simply for the interfacing of a synchronous system to its environment and other synchronous. We also have a wiki for documentation.
