Config BitGen - UnusedPin option not pulling up unused I/Os in Virtex-6 devices

Description

Customers using the BitGen "-g UnusedPin:PullUp" option might notice no pull-ups on unused I/Os after configuration.

Solution

The "-g UnusedPin:PullUp" option is not working in BitGen versions 11.x and 12.1. This is scheduled to be fixed in ISE software version 12.2.

In the meantime, if you want unused I/Os pulled up, use an external pull-up resistor.
