•LUTs: Slice LUTs utilization for 64-bit Data Width
•FFs: Slice Flip-Flops utilization for 64-bit Data Width
•base_LUTs: Baseline LUTs, independent of data width
•base_FFs: Baseline FFs, independent of data width
•LUTs_per_bit: LUTs_for_width_DW = base_LUTs + (DW * LUTs_per_bit)
•FFs_per_bit: FFs_for_width_DW = base_FFs + (DW * FFs_per_bit)
•RO_LUTs, RO_FFs: All SI and MI Read-Only (64-bit data width)
•WO_LUTs, WO_FFs: All SI and MI Write-Only (64-bit data width)
Utilization (LUTs) for crossbar with RW_SI and RW_MI read/write slots, RO_SI and RO_MI read-only slots and WO_SI and WO_MI write-only slots (64-bit data width) is approximately (LUTs[(RW_SI + RO_SI), (RW_MI + RO_MI)] * RO_LUTs%) + (LUTs[(RW_SI + WO_SI), (RW_MI + WO_MI)] * WO_LUTs%); similarly for FFs. (SAMD Crossbar shares no resources between read and write pathways; thus RO% + WO% always = 100%.)
