Compliance
The source code can be obtained.
The list can be composed on
request and contains high level
design tools, compilers for various
processors, syntax validation tools,
build tools, test tools, performance
validation tools, version control
tools, and defect tracking tools.
Plena Voice Alarm System is
compliant.
The modular structure of the Plena
Voice Alarm System software is
documented in the software
architecture documents.
The interfaces between the
modules and to external
components are well defined and
described in the design documents
and external interface documents
(Open Interface). Asserts are used
to validate inputs on component
boundaries.
Design guidelines are in place to
avoid deadlocks. Multi threading
within components is avoided
where feasible and components
have an input command queue for
safe decoupling of threads.
Plena Voice Alarm System is
compliant.
