SLG46170

9.0 Combinatorial Logic

Combinatorial logic is supported via fifteen Lookup Tables (LUTs) within the SLG46170. There are five 2-bit LUTs, nine 3-bit LUTs,

and one 4-bit LUT. The device also includes two Combination Function Macrocells that can be used as LUTs. For more details,

please see Section 10.0 Combination Function Macrocells.

Inputs/Outputs for the fifteen LUTs are configured from the connection matrix with specific logic functions being defined by the

state of NVM bits. The outputs of the LUTs can be configured to any user defined function, including the following standard digital

logic devices (AND, NAND, OR, NOR, XOR, XNOR).

9.1 2-Bit LUT

The five 2-bit LUTs each take in two input signals from the connection matrix and produce a single output, which goes back into

the connection matrix.
