hilomap - technology mapping of constant hi- and/or lo-drivers

    hilomap [options] [selection]

Map constants to 'tielo' and 'tiehi' driver cells.

    -hicell <celltype> <portname>
        Replace constant hi bits with this cell.

    -locell <celltype> <portname>
        Replace constant lo bits with this cell.

    -singleton
        Create only one hi/lo cell and connect all constant bits
        to that cell. Per default a separate cell is created for
        each constant bit.
