MUXF5_L provides a multiplexer function in one half of a Virtex CLB for creating a function-of-5 lookup table or a 4-to-1 multiplexer in combination with the associated lookup tables. The local outputs (LO) from the two lookup tables are connected to the I0 and I1 inputs of the MUXF5. The S input is driven from any internal net. When Low, S selects I0. When High, S selects I1.
The LO output is used to connect to other inputs within the same CLB slice.
