General Description: A DPRAM RPM that worked in 3.1i is un-placable in 4.1i -- PAR quits in the placer with the following error:
"ERROR:Place:1849 - Relative placement of ram SLICE N_SP<2> in rpm U1/hset cannot be placed such that it is routable. This component is the write half of the pair and may not be paired with SLICE data<3>, which is placed 2 slices above it where the read half must exist. Please correct the relative placement problem if possible."
The failure occurs because MAP is swapping the position of 2 LUTs within one of the slices.
