An object-oriented CAE Framework for asynchronous Circuit Synthesis

The paper presents an interactive OSF /Motif-based design framework for high-level specification, analysis and synthesis of asynchronous control c:irc:uits. As novel contributions we propose an object~riented graphical design environment including interfaces to external state of the art asynchronous circuit synthesis tools. The proposed design environment represents a powerful CAE design system including features like geometric representation of abstract graph-based input specifications, menu-based command entry, user-defined configuration of input devices and a comprehensive set of visualisation and manipulation commands. Thus, by using this system, a c:irc:uit designer is able to specify and visualise asynchronous circuit behaviour on a high abstraction level and synthesise the corresponding logic using the built-in algorithms as well as other available non-graphical synthesis tools.
