When the IP integrator tool determines that a potential connection exists among the instantiated IP in the canvas, it opens the Connection Automation feature.

In the following figure, two IP, the GPIO and the UARTLite, are instantiated along with the MicroBlaze processor subsystem.

When you click the Run Connection Automation link, the following dialog box, shown in the following figure, opens.

Figure 2. The Run Connection Automation Dialog Box

The IP integrator determines that there is a potential connection for the following objects:

  • The Proc Sys Rst IP ext_reset_in pin must connect to a reset source, which can be either an internal reset source or an external input port.
  • The Clocking Wizard CLK_IN_1_D pin must connect to either an internal clock source or an external input port.
  • The AXI GPIO s_axi interface must connect to a master AXI interface.
  • The AXI GPIO core gpio interface must connect to external I/Os.
  • The Uartlite IP s_axi interface must connect to a master AXI interface.
  • The Uartlite IP uart interface must connect to external I/Os.

When you run connection automation on each of those available options, the block design looks as shown in the following figure.
