Abstract
The present invention provides integrated circuits with improved logic cells. In one embodiment, an integrated circuit having a plurality of logic cells (LC) is provided, each LC comprising: a lookup table having a LUT output terminal; and, a first multiplexer; wherein, a first multiplexer input terminal is connected to of a first input terminal of the LC, a second multiplexer input terminal is connected to the LUT output terminal, a multiplexer output terminal is connected to a first output terminal of the LC, and a multiplexer select terminal is connected to a second input terminal of the LC so as to select which of the signals appearing at the first and second multiplexer input terminal to pass through; wherein, by coupling in chain the first input terminal of one LC to the first output terminal of another LC, a WLUT chain is formed.
