spare logic is not tied up/down properly after ECO route

achilles

In my ECO step, a number of logic gates are freed up and become spare gates.  They should be connected to VDD or GND selectively.  What command should I use?  The large majority are grounded, but a few are tied high.

Note: 

 I don't have tieHi or tieLo cells in my library; I want to hook up directly. 

When I query the pin, the net shown is "NIL".

    Hi,

    If your library have an inversor cell then you can create tiehigh and tielow cells, easily.

    Regards.
