SpecTRM features Intent
Specifications, a new way to structure system and requirements
specifications that supports system, safety, and software
SpecTRM includes SpecTRM-RL,
an executable requirements specification language. SpecTRM-RL is
used in the construction of executable, analyzable models that are
readable enough to act as the software specification as well. In
fact, SpecTRM-RL is designed to be readable by domain experts with
only minimal training. A unique feature of the Safeware Engineering
approach is that analysis is performed directly on the system
specification. Most approaches to formally evaluating systems
require the extra and often difficult step of translating the system
design into a mathematical modeling language.
editor supports the development of system specifications. Tools for
traceability linking and editing models make SpecTRM an environment
for increasing productivity during specification development.
requirements specifications are also executable models, system
behavior can be simulated directly from the requirements. A
graphical visualization of the system shows the state of the system
during execution. Inputs are fed to the simulator to drive the
system, and outputs are recorded for examination after the
execution. Execution speed is variable, and the simulator can be
single-stepped to examine system behavior in detail.
Most accidents involving
computers can be traced back to omissions or errors in the
requirements specification. A requirements document is incomplete if
it contains insufficient information to distinguish
between desired and undesired behavior. The SpecTRM toolset and
SpecTRM-RL modeling language support the construction of complete
requirements specifications, including some automated analysis for
common omissions and mistakes.
SpecTRM is based on the
Eclipse tool famework, which is designed to permit integration of
tools in one seamless environment. Building SpecTRM on Eclipse means
that SpecTRM can provide a full development environment and API for
extending SpecTRM with custom plugins. This extensibility makes
SpecTRM an excellent tool for research as well as industry.
