Hi all,
I am trying to tell the ISE tools to place DSP48s belonging to a complex multiplier (generated with coregen) close together in a V4FX chip with the following line in my UCF:
INST "DUC_BL.DUC_INST/CPL_MPLY_INST/*/mult_2/m18x18/dsp48_?" RLOC_RANGE=X1Y1:X1Y3;
I am getting the following error:
------------------ ERROR:Map:10 - RLOC_RANGE attribute on DSP48 symbol "DUC_BL.DUC_INST/CPL_MPLY_INST/BU2/U0/mult_2/m18x18/dsp48_0" (output signal=DUC_BL.DUC_INST/CPL_MPLY_INST/BU2/U0/p_cout_2) must be on the start of a set.
I must admit I have not used RLOC_RANGE before...
Thanks, /Mikhail
