I'm using 6/6 mil rules and this is a 44pin 10mm TQFP, as can be seen, the trace has more than adequate clearance. (The other DRC error is due to some dead copper I think, but nothing to be really concerned about.) Can you send an example layout file which shows the problem? I wonder if the image preview is just a little shifted from what is really causing the problem. In the screen-shot you showed, the plane clearance near the via just above what looks like the word core, to the bottom track shown in your DRC violation looks a little close. The too close and insufficient overlap DRCs work by systematically bloating or shrinking geometry, and looking for any shorts or open circuits that might cause respectively. I can't remember exactly, but it might also be triggered by a line segment which doesn't have the required clearance set on it, even though it is not shorting against anything else (perhaps because planes are cleared away by other objects with bigger clearances).

This works well, however I have been wondering if it may be plausible to create a script or plugin that allows you to add the symbol once and then indicate the replication and connections through something like bus notation? Eg: I have a subcircuit with one control input. The micro that connects to the subcircuit is given netnames on the appropriate pins SS1, SS2, SS3, SS4. The control input pin on the subcircuit symbol is given the netname SS[1:4] FWIW, Altium Designer supports this. A friend who uses Altium showed me the feature, and described it as special magic. He was using it though, so it was obviously useful for him. Altium's harnesses are incredibly close to what a number of us have talked about wishing to support in regards heterogeneous arbitrarily nested buses. Altium's buses are homogeneous, and I'm not sure how the above feature would work if the sub-designs had a bus input. I can't recall if this was replicated onto a bus of busses (I'm not sure if Altium supports this anyway), or if they had to be wired up individually. [snip] (This may sound familiar to folks who have used altium - I suspect I am ripping off their notation) Ah - you're familiar with the Altium feature. I am relatively new to gEDA - so I thought I would find out if this is theoretically possible (or been done before) before I start trying to write my own script... Lots is possible, but I'm not sure how you would best go about it. gEDA's bus support is almost non-existent... it is just a graphical nicety, and relies upon named nets.

gEDA-user: My footprints aren't showing up...?
I normally put all footprints under /usr/share/pcb/pcblib-newlib/tom, this used to create an entry under pcblib-newlib called tom. However, as of 1.99z it seems to not be working. It looks like I'll have to downgrade which is a shame because it fixed some bugs with the trace length calculator which I used a bit.

gEDA-user: [PATCH] Drag without selection in gschem
Could someone give this a test and come up with any counter-reasons why
this attached patch is NOT a good idea? I vaguely recall a similar (or
identical?) idea was discussed on the list recently?
I was watching some students using gschem the other week, and noticed
them struggling to move objects due to the fact they had to select them
first. I wrote a patch which lets a drag action operate on whatever is
under the mouse (selected or not).
The user can override the mechanism and get a normal drag-selection
box by holding shift when dragging. This also happens if the user drags
on a blank area of the schematic.
This seems to work here (in conjunction with some other cleanup I pushed
to git HEAD).
I'd appreciate a second pair of eyes on it though, as I just knocked it
together quickly.
Fwiw.. dragging of selected locked objects _does not_ work.. (never did
as far as my brief skim of the code suggests.). I think we ought to fix
that.

Subject: [PATCH] gschem: Don't require select to drag objects
This comes from watching users interacting with gschem and their
clear expectations that objects can be dragged around the canvas
without an explicit selection step first.
When a mouse drag starts on non-selected object, starting dragging
that object rather than forming a box selection.

Re: gEDA-user: subcircuit definition and channelised design
Lots is possible, but I'm not sure how you would best go about it. gEDA's bus support is almost non-existent... it is just a graphical nicety, and relies upon named nets. (I vaguely recall that Altium buses can work like this too if you want) I haven't really used busses properly in Altium - as you described, I've primarily used them just as a graphical nicety while explicitly naming all the connected nets. There may have been a few cases where I named the bus and then connected nets were given the bus prefix, or something like that. But at the time I was just experimenting and didn't really need or find this sort of functionality added much value. (I imagine with a number of 32/64 bit busses something that removed the need to individually name nets would be handy though) In terms of the channelisation functionality my current thought is that I may be able to augment the gnetlist pcb backend to recognise something similar to a bus notation and recognise when a symbol/subcircuit needs to be replicated. (btw - I haven't yet started looking through the gnetlist backend sourcode or doco so if this sounds like something impossible - feel free to give me a heads up :) cheers, Geoff Swan ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
