4.1. Bridges

Bridges affect the way Platform Designer transports data between components. You can insert bridges between master and slave interfaces to control the topology of a Platform Designer system, which affects the interconnect that Platform Designer generates. You can also use bridges to separate components into different clock domains to isolate clock domain crossing logic.

A bridge has one slave interface and one master interface. In Platform Designer, one or more master interfaces from other components connect to the bridge slave. The bridge master connects to one or more slave interfaces on other components.

Figure 109. Using a Bridge in a Platform Designer SystemIn this example, three masters have logical connections to three slaves, although physically each master connects only to the bridge. Transfers initiated to the slave propagate to the master in the same order in which the transfers are initiated on the slave.
