MARTE — SAM: General

SAM: General] Time-triggered system modelling are supported in some way by the TimeTableDriven scheduling policy (fig 10-19). However, it is not clear how to specify a table (format) and where (e.g. Scheduler stereotype, schedule: OpaqueExpression attribute?). Some examples for time-triggered system modelling should be provided in MARTE.

Schedulers of the other variants of SchedPolicyKind use configuration parameters which are expressed in the SchedulableResource::SchedParameters attributes. To be consistent, when modeling TimeTableDriven scheduling, the SchedParameters stereotype SHALL include a tag definition SchedParameters::tableEntry of type OpaqueExpression which SHALL store the information necessary to schedule the SchedulableResource according to the algorithm of the Scheduler's time-triggered, table-based scheduling.

The algorithm of the time-triggered, table-based scheduler SHALL be expressed within the Scheduler::schedule's OpaqueExpression.
