9.1i NgdBuild - WARNING:NgdBuild:889 - Pad net X is not connected to an external port in this design

Description

Keywords: Buffer, IBUF, OBUF

When I'm running Translate, I get the following warning:
WARNING:NgdBuild:889 - Pad net X is not connected to an external port in this design.
What does this mean?

Solution

A pad net is a net that drives an IBUF or is driven by an OBUF and a PAD is the only other legal connection. This warning occurs when there is no pad connected to the net and NGDBuild will add one for you. If the net referenced is not intended to be connected to a pad, remove the IBUF or OBUF.
