Formalizing Chisel Specifications

Graphical description techniques are especially useful in the early development phases like requirements engineering. There, often a trail-and-error approach is applied to develop a first system specification. However, even there a precise meaning of those description techniques is necessary, especially in trial-anderror phases based on a service-oriented description of the requirements to check for consistency. We introduce a formal semantics for the graphical language Chisel and show how this formalization can be applied to model checking to support a methodical development of interacting features.
