现象

用PROHIBIT约束禁止指定FF BEL后整个slice也被禁止，导致寄存器无法布局

根因

帖中未明确

可尝试的处理步骤

• set_property PROHIBIT true [get_bels -filter {TYPE == AFF2 || TYPE == BFF || TYPE == BFF2 || TYPE == CFF || TYPE == CFF2 || TYPE == DFF || TYPE == DFF2 || TYPE == EFF2 || TYPE == FFF || TYPE == FFF2 || TYPE == GFF || TYPE == GFF2 || TYPE == HFF || TYPE == HFF2} -of_objects [get_sites -range {SLICE_X0Y0 SLICE_X2Y10}]]
• set_property BEL AFF [get_cells register/*]
