for subcircuits (.subckt ... .ends pair with cellname and pin names and pin order, but no contents) are automatically treated as black- box circuits if found and if the "-blackbox" option is passed to the "lvs" (scripted) command. The "equate pins" command can be used outside of a comparison to force two circuits (black-box or otherwise) to be matched by pin name (if not a black-box circuit, then this is a provisional name match, as a circuit comparison will order based on connectivity first, not pin names). So two sets of black-box circuit libraries can be used as long as their pin names match. One hack added to ignore the "!" at the end of global names when comparing pin names for matching. Otherwise, pin names must compare by case-insensitive string match.
