General Description:
How to convert tristate multiplexers to LUT multiplexers using
the syn_tristatetomux attribute?
Forces Synplify to analyze each net in your design driven by tri-state
drivers and convert the drivers into a mux. This is done if the number
of tri-states drivers on the net is less than the integer value specified
with this attribute.
Note: All drivers on the nets that could be converted to muxes must
be tri-state drivers, otherwise the conversion fails and a warning is issued.
