There are several ways to use an existing interface in IP integrator. Use the Board window to instantiate some of the interfaces that are present on the SP701 board.
Navigate to the Windows>Board.
Select the Board window to see the interfaces present on the SP701 board.
In the Board window, notice that the DDR3 SDRAM interface is connected as shown by the circle
in the following figure. This is because you used the Block Automation feature in the previous steps to connect the MIG core to the board interfaces for DDR3 SDRAM memory.
From the Board window, select UART under the Miscellaneous folder, and drag and drop it into the block design canvas.
This instantiates the AXI Uartlite IP on the block design.
From the Board window, select LED under the General Purpose Input or Output folder, and drag and drop it into the block design canvas.
This instantiates the GPIO IP on the block design and connects it to the on-board LEDs.
Next, from the Board window, select FPGA Reset under the Reset folder, and drag and drop it into the block design canvas.
This connects the CPU push button reset to the MIG core IP.
The block design now should look like the following figure.
