6 Conclusions
We have shown that message sequence charts are sensitive to various se­
mantic interpretations. Under different semantics, different race conditions
may occur.
We have proposed and implemented a tool which can be used to ana­
lyze message sequence charts to locate and visualize design errors as early
as possible in a design cycle. The tool conforms to ITU recommendation
Z.120. We have noted that extensions of the tool, to gently integrate for­
mal verification techniques further into the design process, are possible. It
is our intention to use the formal representation of MSCs described here as
a vehicle for exploring such extensions.
