	The LibreSilicon Pad Cell Generator is an extension of the [[StdCellLib\|Standard Logic Cell Library generator]], which besides the driver logic also dynamically generates the mixed signal parts needed for over current and static discharge protection and providing the currents needed for doing useful things with an actual physical chip, like driving an LED or a small motor.
