Node Model Example Instance Sample Clauses

Node Model Example Instance. Figure 5.6: Node domain example model instance An exemplary model from the Node domain is shown in Figure 5.6, i.e. the internal structure of a Cluster. The example consists of two Nodes, one OffChipNetwork, and two PowerSupplys. The OffChipNetwork, which represents e.g. a TTEthernet network or an EtherCAT network, has three attached OffChipNetworkInterfaces. Three OffChipNetworkPorts (represented by black connectors) at the Nodes and at the right hand side of the OffChipClusterGateway are connected to these OffChipNetworkInterfaces. The NetworkInterface located at the left side of the OffChipNetwork in the example is connected to an OffChipNetworkPort of the containing Cluster. As pointed out in Section 5.2.1.2, the Cluster’s OffChipNetworkPort can be connected to the OffChipNetworkInterface of an OffChipNetworkGateway. Since Clusters only represent a logical grouping of platform elements, the OffChipNetworkGateway (that is used to describe the connection of the off-chip networks of two different clusters) resides at the cluster- domain. In contrast to that, OnChipOffChipGateways (see Section 5.2.3.2 for an example) and NetworkInterfaces (see Section 5.2.5.2 for an example) are used to route communication from different levels of the architecture. Hence, OnChipOffChipGateways and NetworkInterfaces reside at the lower of the two architecture levels that are connected by them (tile-domain, and processor-domain, respectively) and their interface to the containing architecture level is expressed using specializations of IPlatformExport (OnChipOffChipExport and OnChipNetworkExport, respectively). Each of the two Nodes present in the example is connected to an independent PowerSupply. The connection is established via PowerOuts at the PowerSupplys and PowerIns attached to the Nodes. The information about the power supply of Nodes can be considered during safety analysis (e.g., shared vs. separated power supply)
