The HOOD (Hierarchical Object Oriented Design) method could be a
solution.

HOOD was initially developed to support Ada, but similar code generation
rules have been defined to target real-time C applications as well, from
the same high level design description. These C code generators must
generally be customized to perfectly fit RTOS capabilities and project
requirements (coding rules, ..), but this should not be a problem.

In a HOOD design, it is possible to identify passive or active modules
and their interactions. Each module provides operations that can be
"constrained" to specify a communication protocol (synchronous,
asynchronous, IT, protected access, ...).

General information about the HOOD method may be found at:
	www.hood-method.org

Information about our HOOD tool (STOOD) with Ada and C-RealTime code
generators:

STOOD will be presented at next SigAda exhibition (TNI's booth)
