Does Vivado Synthesis support LUT combining by default?

Description

Does the Vivado Synthesis tool support LUT combining by default?

Solution

Starting in 2013.1, the Vivado Synthesis tool does support LUT combining by default.

To disable LUT combining, use -no_lc switch either via the Synthesis settings window within VIvado IDE or by passing it to the synth_design Tcl command.
