As shown in the following figure, a "lightning bolt" icon indicates a "smart" connection. Smart connections have intelligence built in to help you manage the connection. For example, right-clicking a block with an AXI interface allows you to:
- Group AXI signals into a bus.
- Separate AXI signals from a Bus
- Connect to other ports with the same number of AXI connections.
No port data type checking is performed and any AXI ports with the same number of ports are allowed to connect.
In another smart connection example below, right-clicking the Accumulator block output, selecting BlockConnect, and double-clicking Scope creates a smart connection to the Scope block. The Gateway Out block is added automatically.
If a second connection is made to this Scope block, a second port is automatically added to the Scope. The driving signal name is also used to name the signal driving the scope.
