    What do you mean you can't find VDD? You create VDD yourself!
    Really, I am not Sam.

    Re: Cannot find vdd in the design

    In many standard cell libraries, supply rails are not shown as
    wired pins, but embedded as global named nets in the lowest
    level schematic (if schematics exist at all, in that library) or
    in the text based gate description (e.g. verilog).

    Maybe you are looking for "vdd" when you should be looking
    for "vdd!" (global power net).

    But I don't know from modern-day logic design / synthesis,
    or what the tool set may be, only your acronym.
