Many times this is a box with pins Sometimes just a box with attributes, using pins supplied by pins2gsch (http://www.gedasymbols.org/user/john_doty/tools/pins2gsch.html). > 2.

Save reusable, pre-layed-out subcircuits somehow The missing piece is the interpretation of hierarchical netlists. In geda-gaf, it’s not terribly difficult to script the construction of hierarchical netlists. My ASIC layout contractor takes hierarchical SPICE and turns it into hierarchical layout, but the downstream tools for printed circuits aren’t usually so nice.
