3.1i Spartan-XL PAR - Placer fails to place TDO comp when Exact Guide is used.
Keywords: guide, guided, TDO, unplaced, unrouted
A case has been seen where the placer failed to place the TDO
comp when Exact Guide is used. It works okay if guide was not used.
Work around for guided PAR is to use a PCF constraint to LOC the TDO comp:
COMP "TDO_O" LOCATE = SITE "TDO" LEVEL 0 ;
This problem was fixed in version 4.1i.
