Asynchronous circuits are becoming increasingly important in system design for Internet of Things, where they orchestrate the interface between big synchronous computation components and the analog environment, which is inherently asynchronous and has high uncertainty with respect to power supply, temperature, and long-term aging effects. However, wide adoption of asynchronous circuits by industrial...
Elastic circuit design is a revolutionary step in VLSI design paving the way for commercial adoption of asynchronous design techniques. With a growing trend of synchronous-asynchronous CAD tool flow integration, this paradigm shows promise to survive market forces of the semiconductor industry mainly due to scope for reuse of synchronous functional blocks and IP cores, and co-existence of synchronous...
The paper proposes a new formal model for describing asynchronous behaviours involving the interplay of causality, concurrency and choice. The model is called Waveform Transition Graphs. Its main aim is simplifying the learning process for industrial engineers in accessing powerful synthesis tools provided for Signal Transition Graphs by sacrificing some of the expressive power of the latter. This...
Analog/mixed-signal (AMS) systems are rapidly expanding in all domains of information and communication technology. They are a critical part of the support for large-scale high-performance digital systems, provide important functionalities in medium-scale embedded and mobile systems, and act as a core organ of autonomous electronics such as sensor nodes. Analog and digital parts are closely inter-mixed,...
