tribuf [options] [selection]
This pass transforms $mux cells with 'z' inputs to tristate buffers.
merge multiple tri-state buffers driving the same net into a single buffer.
convert tri-state buffers that do not drive output ports to non-tristate logic. this option implies -merge.
convert all tri-state buffers to non-tristate logic and add a formal assertion that no two buffers are driving the same net simultaneously. this option implies -merge.
