| output | used for pass transistors to force either the source, drain, or both to be labelled as an output. This is useful for the PININFO directive emitted by prs2net. If the value v has bit zero set, then the source is marked as an output node. If v has bit one set, then the drain is marked as an output. By default, a node is considered an input if it does not have a production rule driving it. | | | output | used for pass transistors to force either the source, drain, or both to be labelled as an output.
