Abstract

System-level design of discrete-continuous embedded systems is a complex and error-prone task. While existing design languages like SystemC and its extension to the mixed-signal domain, SystemC-AMS, are supported by tools and libraries, they lack both mathematical precision and intuitive, abstract design notations. Graphical design notations with formal foundations such as HyCharts suffer from the lack of tool support and acceptance in the developer community. To overcome the deficiencies of both approaches, we present a design flow from graphical HyCharts to SystemC-AMS designs. This design flow uses a formally founded refinement technique to ensure the overall consistency of the design.
