  text: This article presents an approach, which combines theorem proving-based refinement
    with model checking for state based real-time systems. Our verification flow starts
    from UML state diagrams, which are translated to the formal B language and are
    model checked for real-time properties. By means of the B language and a B theorem
    prover, refined state diagrams are verified against their abstract representation.
    The approach is presented by means of the refinement of a digital echo cancellation
    unit.

  text: We present a rigorous but transparent semantics definition of SystemC that
    covers method, thread, and clocked thread behavior as well as their interaction
    with the simulation kernel process. The semantics includes watching statements,
    signal assignment, and wait statements as they are introduced in SystemC V1.O.
    We present our definition in form of distributed Abstract State Machines (ASMs)
    rules reflecting the view given in the SystemC User's Manual and the reference
    implementation. We mainly see our formal semantics as a concise, unambiguous,
    high-level specification for SystemC-based implementations and for standardization.
    Additionally, it can be used as a sound basis to investigate SystemC interoperability
    with Verilog and VHDL.
