Problem Title:
Map: Removes logic that is tied to pads locked to Unbonded pins.


Problem Description:
Keywords: Map, Pin Locking, LOC, UNB, Unbonded, Pad, Pin,
	  Trimmed

Urgency: Standard

	     unbonded pin, map removes the pin and the related
	     logic.




Solution 1:

The workaround is to lock the pad to a bonded pin and run through par. Then edit
 the pcf to loc the pad to the correct unbonded pin. Then continue running the t
ool.

For example the .pcf will look like this when you open it.
comp "comp_name" LOCATE = SITE "P12" LEVEL1

You need to change it to:

comp "comp_name" LOCATE = SITE "UNB11" LEVEL1
