Hi, there:
I remembered there was a constraint that can prevent MAP from removing floating input pins? What is it?
Thanks. Kelvin
How to prevent MAP from removing floating inputs?

-u flag on the command line.
You may also need to tell your synthesiser.

The net constraint "S" will block trimming on an undriven or unloaded net. An example of UCF syntax is:
NET "net_name" S ;
When map is run with the "-u" switch, this constraint is automatically applied throughout the design.
