6.5 Latency Analysis with Instance Models
The above two latency analyses have illustrated the possibility of performing latency analysis on declarative models. However, such an analysis is not always possible on declarative models. For example, if the latency calculations are dependent on particular execution platform bindings the analysis must be performed on an instance model. This is the case if the connection latency is different for communication within the same processor as compared to communication between processors over a network.
In those cases the analysis methods will want to operate on the flow information recorded with the instance model. The relevant parts of the instance model have been shown in Figure 36.
