End-to-end flow latency analysis on declarative AADL models follows the same algorithm as
that for instance models. Note that in this case the end-to-end flow latency in this case is
calculated in terms of the immediate subcomponents in the component hierarchy, not in terms of
the leaf components. In other words, the flow specification latency property value of the
immediate subcomponent or its partitionLatency property is used in the calculation. The flow
specification latency property value may have been explicitly specified by the user, or it may
have been derived by calculating its flow implementation’s latency (see Flow Implementation
Latency Analysis).
