2.1i Constraints Editor: Pullup/Pulldown option is N/A for inputs

Description

General Description:

In the Ports tab, the Pullup/Pulldown option is N/A

for inputs. How can the Pullup/Pulldown option be

implemented for inputs?

Solution

The workaround is to edit the UCF file manually or

to instantiate the PULLUP/PULLDOWN component

in the design.

This is suppose to be fixed in a future release of

the software.
