Vsupply pin (or pin group)

All device under test power supply and external voltage source pins (excluding ground pins), including both positive- and negative-potential pins.

NOTE 1 Generally, it is permissible to treat equal potential voltage source pins as one Vsupply pin (or pin group) and connect them to one power supply.

NOTE 2 When forming Vsupply pins (or pin groups), combining Vsupply pins with significantly different supply current levels is not recommended as this would make it difficult to detect significant current changes on low-supply-current pins.
