gEDA-user: 200 bugs, warts and feature requests
Hi. When I do projects, schedule is usually a bit tight and I can't afford to dive into every issue I stumble on the way. So I make a quick note in my digital notebook zim. This may be bugs, little ideas for better usability, or issues with certain not so brilliant features. Of course, most often, I never return to the subject. The list of notes grew over the years. Currently, it is at about 200 items. Is there anything sensible I might do with it? Dump it wholesale to the mailing list? Add items to the source tracker? Pick one item a day and present it to the mailing list for comments? ---<)kaimartin(>--- PS: This is what the last couple of lines look like: /-- • pcb wart: rats don't print in the eps HID • gschem room for improvement: If an autosave backup is found, the dialog should offer to show the diff of the two files. • gschem usability improvement: If a symbol contains slots, insert should optionally add all slots at once with slot numbers automatically incremented. • gschem usability: The add text dialog should automatically apply the current text when the mouse leaves the dialog. • gschem usability: The add text dialog should contain widgets to set text attributes like size, color, orientation, • gschem usability: Accel to increment/decrement text size on [s]/[shift-s] similar to pcb \-- -- Kai-Martin Knaak tel: +49-511-762-2895 Universität Hannover, Inst. für Quantenoptik fax: +49-511-762-2211 Welfengarten 1, 30167 Hannover http://www.iqo.uni-hannover.de GPG key:http://pgp.mit.edu:11371/pks/lookup?search=Knaak+kmk&op=get ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

So I put these lines in a local gnetlistrc: (hierarchy-uref-separator "") (hierarchy-netname-separator "") In addition, I set the refdes of the subsheet symbol to a single digit. That way, the refdeses stand a chance to be readable in in silk with a three layered hierarchy. ---<)kaimartin(>--- -- Kai-Martin Knaak tel: +49-511-762-2895 Universität Hannover, Inst. für Quantenoptik fax: +49-511-762-2211 Welfengarten 1, 30167 Hannover http://www.iqo.uni-hannover.de GPG key:http://pgp.mit.edu:11371/pks/lookup?search=Knaak+kmk&op=get ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

If the symbol for the subcircuit has refdes X15, and it contains a component with refdes C42, the refdes in the flattened netlist created by gnetlist is X15/C42.

gEDA-user: Hierarchy Refdes and Component Values
I have a schematic with seven instances of a schematic, a hierarchy. I want to give different values to the resistors in each of the sub-circuits. For example, I have S1 thru S7. In S1, I want R1=100, in S2, I want R1=1k, etc. Is this possible with hierarchy? How do the components in the hierarchy get assigned refdes values? tomdean ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

I think there's nothing wrong with file=? in the symbols. It indicates that the you have failed to supply a required filename. (create-file-info-list), the "WTF?" function in spice-sdb, should issue a diagnostic if the file name is "?". Right now, all that results from substituting "unknown" is that it silently omits the file, which is surely wrong behavior. You won't even know there's a problem until you run SPICE, which has its own troubles with generating diagnostics that clearly identify the problem. There are other problems with that function, too. Even if you give spice-sdb no reason to inspect included file contents (use -I --nomunge), it does so anyway. This can make building a subcircuit library tricky. If you want the automatic file inclusion for subcircuits to work you must build the library in topological order, because the included file must exist at netlist generation time even if you're not including it at that time, and have no dependence on its contents.

It is lucky (for us) that you spotted it so soon after the bug was introduced. It was a nasty unobvious sort of bug, and to be honest, I'm still not 100% sure what expected API rules of calling the affected function are. It appears that it is doing some clean-up for an operation it does not directly initiate. (For something done before the function was called). The patch in question had the side-effect of causing the function to exit early when no work was to be done (where the function did not have to add any rats to process). It seems that the clean-up it skipped by doing so was actually necessary to flush out connections from the current net, before moving onto the next net in the netlist. -- Peter Clifton Electrical Engineering Division, Engineering Department, University of Cambridge, 9, JJ Thomson Avenue, Cambridge CB3 0FA Tel: +44 (0)7729 980173 - (No signal in the lab!)
