The I/O Planning view layout provides an interface to selectively prohibit port placement onto individual I/O pins, groups of I/O pins, or I/O banks. You can select and prohibit pins in the Device, Package, and Package Pins windows.

To prohibit I/O pins or I/O banks:

  1. Select the I/O pins or I/O banks in the Device, Package, or Package Pins window.
  2. Right-click, and select Set Prohibit.
Prohibited pins are indicated by:
  • Slashed circle in the Device window and Package window (see the following figure)
  • Check mark in the Prohibit column of the Package Pins window


Tip: You can clear prohibits from the Prohibit column of the Package Pins view. Select an individual prohibit or use Ctrl+A to select all pins, right-click, and select Clear Prohibit. Alternatively, you can use a Tcl command to clear the prohibit, for example: set_property prohibit 0 [get_sites U17].
