    Look into the part’s chips.prt file. In this file, scroll down to the bottom, you may

    find a line in the ‘body’ section  listed something similar as –

    POWER_PINS='(GND1:10; GND2:11; GND3:12; GND4:13;VCC1:20;VCC2:21)';

    This is where the power and ground pins for a part can be listed if the

    librarian does not wish to physically show them on the symbol.

    They will be connected to the net names specified in the POWER_PINS

    line.

    Don't forget the use of the POWER_GROUP property in the event he wants to change any of the voltages.
