Slave to Master Interface Switch Connectivity Map
The table shown the previous figure allows the configuration of the switch to optimize connectivity. By default, full connectivity is enabled meaning that every slave interface is connected to every master interface. Deselecting a checkbox removes the connection from the slave interface listed in the column to the master interface in the row. Removing connections is desirable when it is known that a slave interface is never going to send transfers to a particular master interface. This removes unnecessary logic resulting in smaller area utilization, routing and logic complexity.
Important: Do not leave any interfaces without
connectivity. Every slave interface must have connectivity to at least one master
interface. Conversely, every master interface must have connectivity to at least one
slave interface.
