The Package Pins window contains several data types that display in columns similar to a spreadsheet. In this window, you can:

  • Flatten, filter, and sort data.
  • Move, hide, and configure columns to display and compare the various multifunction pins.
  • Directly edit certain cells by entering text or selecting a value from drop-down menus.

The Package Pins window includes the following information:

  • Type column identifies multifunction pin types.
  • Config column shows the pin definition of the multifunction pin after you set the device configuration mode.

    Note: Many device configuration modes use multifunction pins. For more information, see Setting Device Configuration Modes.

  • Other columns contain information about logic or configuration modes involving multifunction type pins.
  • Information identifies conflicting multifunction pins for designs that contain GTs, memory controllers, or PCI™ logic.
  • Asterisks indicate the I/O standard or attribute, such as drive strength or slew type, is not set to the default generated by the system.
Figure 1. Package Pins Window

In the Package window, the following symbols indicate the function of multifunction pins:

  • Clock capable pins display as a hexagon icon
  • VREF pins display as a small power icon

    For Zynq UltraScale+ MPSoCs, pins controlled by the configuration of the Zynq UltraScale+ MPSoC IP display as a square icon .

    Important: Dedicated I/O pins are dedicated to the targeted device not to the bank. For example, dedicated I/O pins such as VCCO and GND are device-specific rather than bank-specific.
