Some embodiments provide a configurable integrated circuit with a tile. The tile has a first input multiplexer (IMUX), a second IMUX, and a look up table (LUT). The first IMUX is configured as a two-input multiplexer. The second IMUX is also configured as a two-input multiplexer. The LUT is also configured as a third two-input multiplexer. An output of the first IMUX is connected to the first input of the LUT, an output of the second IMUX is connected to the second input of the LUT. A third input of the LUT accepts a selection bit.
