When you create a design in IP integrator, you add blocks to the diagram, configure the blocks as needed, make interface-level or simple-net connections, and add interface or simple ports.

Making connections in IP integrator is designed to be simple. As you move the cursor near an interface or pin connector on an IP block, the cursor changes into a pencil. You can then click an interface or pin connector in an IP block, hold down the left-mouse button, and then draw the connection to the destination block.

A signal or bus-level connection is shown as a narrow connection line on a symbol. Buses are treated identically to individual signals for connection purposes. An interface-level connection is indicated by a more prominent connection box on a symbol, as shown on the SLMB interface pin in the following figure.

Figure 1. Pins on a Symbol

When you are making connections, a green check mark appears next to any compatible destination connections, highlighting the potential connections for the signal or interface.

Figure 2. Signal or Bus Connection on a Symbol

When signals are grouped as an interface, you can quickly connect all of the signals and buses of the interface with other compatible interface pins. The compatible interfaces are also identified by a green check mark. AMD provides many interface definitions, including standardized AXI protocols and other industry standard signaling; however, some legacy or custom implementations have unique IP signaling protocols. You can define your own interface and capture the expected set of signals, and ensure that those signals exist between IP.
