PragmaDev – Core technology
Specification and Description Language
SDL main characteristics:
• ITU-T standard (Z.100),
• Best modeling language for event
19/04/2010
driven systems (Telecom
standards),
• Object oriented (since ’92),
• Formal (complete and non
ambiguous),
• A UML profile based on SDL has
been standardized,
• Increase quality by a ratio of 5,
• Reduces development time by
30%.

19/04/2010
TASTE an assert-project / ESA / Confidential
A graphical debugger
for fully formal models
based on the model
semantic
• Set breakpoints and step
in the diagrams,
• Externally defined or
interactive operator
calls,
• Dynamic traces,
• Connecting an external
tool is possible through a
socket.

• Control of memory allocation,
• C scheduler provided,
• Generated code is legible,
• Generation profile wizard,
• Royalty free,
• Documented for customization.

PragmaDev – Code generation and debug
The Model debugger relies on a traditional C debugger or cross debugger
to provide graphical debugging.

PragmaDev – Model debugger
Depending on the
integration model:
• Relies on the target
semantic: processor
and RTOS,
• Relies on the SDL
semantic.
Debug in the model:
• Breakpoints, stepping,
in the diagrams or in
the generated C files,
• Dynamic MSC traces,
• Connecting an external
tool is possible through
a socket.

• Based on TTCN-3
international standard:
• Data types definitions,
• Templates definitions,
• Test cases,
• Execution control.
• Connects automatically to
the Simulator:
• Breakpoints in the
model or in the test
suite,
• Verdict displayed in the
trace.
