Can gschem do hierarchical designs with sub sheets?
Yes. Sub sheets are represented by special symbols on the top level schematic. You can find an example for a hierarchical design in the doc section of gschem (geda-doc/examples/gTAG/gTAG.sch). Currently, there is no way to automatically build a sub sheet symbol from an actual sub sheet. The sub sheet symbol has to be drawn manually. Any patches or external scripts that get the job done would be greatly appreciated. A source= attribute attached to the sub sheet symbol gives the path to the sub sheet file. The pins of the symbol correspond to ports from top sheet to sub sheet. These ports should correspond to a refdes of a port symbol on the sub sheet. The port symbols in the default library of geda are in-1.sym and out-1.sym. Use the hierarchy menu to navigate within the hierarchy of sub sheets. Alternatively, you can navigate with the page manager. To convert a hierarchy to a netlist just call gsch2pcb on the top level schematic. By default, net names and refdes’s of components are str
