Robust and Energy-Efficient Hardware: The Case for Asynchronous Design

The current technologies behind the design of semiconductor integrated circuits allow embedding billions components in a singe silicon die, enabling construction very complex tiny space, dissipating little energy and producing huge amounts useful computational work. However, levels integration for electronic similar materials are not easily managed, as parameter variations grow steadily, making tasks increasingly challenging. Synchronous techniques have dominated digital system landscape many decades, but their costs hard to cope with. Asynchronous particularly quasi-delay insensitive promises deal with same challenges more gracefully advanced nodes, possibly irrevocably future technology nodes. This article proposes review state art using asynchronous circuit achieve energy-efficient robust design. In particular, definition comprises addressing several aspects which is expected be to, including: (1) voltage variations; (2) process (3) temperature (4) aging. Besides energy-efficiency all mentioned robustness aspects, this work also approaches some state-of-the-art tools available design, points desirable research development conducted these subjects future.
