“…The LEMA tool [26] includes multiple reachability analysis methods. It includes both an explicit state method originally used for timing verification that leverages zones and difference bound matrices (DBMs) to represent the continuous state space [27] and implicit state methods that use binary decision diagrams (BDDs) and SMT solvers [28].…”

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 intermixed, hence demanding AMS design methods and tools to be more holistic. In particular, the emergence of "little digital" electronics inside or near analog circuitry calls for the increasing use of asynchronous logic. To cope with the growing complexity of AMS designs, formal methods are required to complement traditional simulation approaches. This paper presents an overview of the state-of-the-art in AMS formal verification and asynchronous design that enables the development of analog/asynchronous co-design methods. One such co-design methodology is exemplified by the LEMA-Workcraft workflow currently under development by the authors .

“…The tool WORKCRAFT 3 aims to provide formal methods for specification and synthesis of asynchronous circuits. Formal verification of AMS circuits is performed by the tool LEMA [5]. The proposed workflow leverages both of these tools to design mixed-signal circuits with asynchronous digital control.…”

This paper presents a novel workflow for the design of mixed-signal systems. Current methods rely on synchronous control logic and full-system simulation, which might lead to suboptimal results and even project respins due to critical errors. The proposed workflow aims to combine state-of-the-art tools for asynchronous circuit design and formal verification of analogue systems in a unified environment. The effectiveness of this methodology is demonstrated by the analysis of a buck converter.
