For tapeouts, integrating Analog IP, or other non-standard use cases, Chipyard supports specifying a custom ``ChipTop`` using the ``BuildTop`` key.
An example of a custom ChipTop which uses non-standard IOCells is provided in `generators/chipyard/src/main/scala/example/CustomChipTop.scala <https://github.com/ucb-bar/chipyard/blob/main/generators/chipyard/src/main/scala/example/CustomChipTop.scala>`__

The ``EmptyChipTop`` example can be built with ``make CONFIG=EmptyChipTopConfig TOP=EmptyChipTop``.
