Detailed Description

A subgraph is a set of items that are electrically connected on a single sheet.

For example, a label connected to a wire and so on. A net is composed of one or more subgraphs.

A set of items that appears to be physically connected may actually be more than one subgraph, because some items don't connect electrically.

For example, multiple bus wires can come together at a junction but have different labels on each branch. Each label+wire branch is its own subgraph.
