anil chatrathi

 Hi,

I have a requirement add dummy power net which has to conected to macro pins.

with "addNet  -physical only "   I could  able to create the net. But it is not created as global net.

When I do a globalnetconnection to the macro pins I am getting an error that the net created is not a global net.

can any one suggest me to  add a global net and conect it to a pin    in encounter.

Thanks and Regards, Anil

  • Hi Anil,

    Try the following depending on whether it is power or ground:

    addNet -physical vddcore

    addNet -physical gndcore

    setNet -net vddcore -type special

    setNet -net gndcore -type special

    dbSetIsNetPwr vddcore

    dbSetIsNetGnd gndcore
