I was trying to generate a 4-bit Baugh-Wooley multiplier and i did that. Then i was trying to optimize it.

When i tried to locate the position for z-register i got the following error.

constraints (LOC=SLICE_X2Y18) which requires the combination of the symbols 

listed below to be packed into a single SLICEM component.
