General Description: The placer reports the following internal error:
"INTERNAL_ERROR:Place:basplbscore.c:615:188.8.131.52 - attempting to provisionally place multiple components into the same site." After giving hundreds of such errors PAR gives a placer score and completes the par with a routed NCD file. This is a PCI design targeted to CB228 package. Check data in bugcases directory."
The problem has been traced to the fact that a data file has a pad assigned multiple times to the same IOB bank, leading to the conflict report in the error message.
