2.1.5 Look-up Tables

Manually configured logic functions.

The CLB Synthesizer provides a four-bit LUT implementation.

To use the LUT, drag and drop the LUT symbol onto the canvas and set the output (Q) states in the properties panel according to the required logic function.

Note: Although the CLB architecture consists of four input LUTs, it is no guarantee that a manually entered LUT will be implemented entirely in one BLE LUT in the same way it was drawn. The synthesis process will always produce the logic equivalent to this LUT, which may be simplified or distributed over several actual BLEs.
