Re: gEDA-user: schematic hierarchy netlist problem
OK, thanks for the response. Attached is a very simple hierarchical design. The .pcb and .net files were generated by gsch2pcb --skip-m4. You can see the U?-? in the .net file.

Re: gEDA-user: schematic hierarchy netlist problem
Found the answer to my own question by playing around a bit. The pins on the top level symbol didn't have a pinnumber attribute - I didn't think I needed them since they are meaningless. When I put them in, the problem goes away. I've made them invisible so as not to give meaningless info on the top level schematic.

gEDA-user: schematic hierarchy netlist problem
Been experimenting with hierarchical design with gschem. When I generate the netlist using gsch2pcb I get a U?-? on every net that goes to one of the io objects. As per the wiki (I think), I've used an in-1.sym in the sub schematics where they get input from the top level schematic, and an out-1.sym for outputs to the top level. In each case, I've set the io symbol's refdes to the same as the pinlabel attribute of the corresponding pin of the top level symbol. The generated netlist picks up all the things it should do from the sub pages, eg: unnamed_net5S2/R2-1 S2/U1-1 SW1-2 U?-? I'd much appreciate it if someone could tell me where I'm going wrong. -- Peter Baxendale [EMAIL PROTECTED] ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
Re: gEDA-user: schematic hierarchy netlist problem
It looks like it is partially working. Your net list has S2/R2-1 which is one hierarchical level down from SW1-2. Is the U?-? the symbol that has the lower level schematic?
