Java Based Modeling And Simulation Of Digital Systems

Hardware/Software systems nd an ever increasing market. The modeling, partitioning, (co-)simulation and synthesis of such systems requires a uniform language of description for hardware and software on all levels of design. This article presents such a language in form of Java. The article concentrates on the qualiication for modeling and simulation of this language with respect to hardware. It is shown that the object orientation of this language enables it to be used on all levels of abstraction of hardware design. The main point is the construction of a class library for modeling with conservation of the simulation semantics at diierent levels of abstraction. This will be illustrated in particular on register transfer level (RTL). A parallel, thread based RTL simulation system has therefore been fully integrated into the class library used for modeling.
