The difficulty is that none of the three models I generated represents a particular real part: opbw and opgain are highly idealized (as is Al's parameterized gnucap model). opmediocre is close to something you could actually construct on Si, but is not (as far as I know) an accurate model of any particular standard device.

I've also made progress on symbols for them, but there's more to be done. I'm also thinking about yet another SPICE back end for gnetlist. Stuart's spice-sdb works great for VLSI if you turn off the heuristics intended for simulating boards (--nomunge), and his documentation is superior, but I don't think the heuristics work very well.

Yup, and in some sense this is even true of free material. When I have put together download scripts, my checklist is: - rollover to a series of URLs - accept uncompressed, .gz, and .bz2 versions transparently - include an sha1sum to confirm you got what was intended - the last URL in the rollover list is a URL I control For the non-redistributable case, the last item is problematic. You still need it, but it has to be somehow not publicly accessible, so it can qualify as a legal backup copy. If the original becomes unavailable, the backup can become the reference copy for a clean-room reimplementation. So this trick becomes a way to defer and prioritize development of truly free models, not eliminate them. - Larry ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

gEDA-user: Copper-free area in footprint
Hi, Currently I make a footprint for an Amphenol SIMLOCK adapter (http://www.amphenol.de/downloads/C707_10M006_500_2.pdf) and there are a few area where copper/wires not allowed. My best idea is, that I do it by pads which have a zero width and a specified clearance. Unfortunately, those will have a rounded corner, so rectangular corner seems impossible (I can reduce the radius, if I make it from more pieces, but it never will be zero). Is there a better way?

I chopped up the .sch file and ran it as small chunks through gattrib

Re: gEDA-user: Database on symbols, footprints and other (was Re: gattrib)
If you have a reference design that you're trying to modify or extend getting a working set of symbols takes most of the time. And reference designs are the open source way. You can distribute symbol files with a reference design. No problem. Still, I'd expect to have to tweak them. Indeed, design reuse is a strength of the project symbol approach. Change packages, even parts selection (have symbols fast_npn.sym, etc, choose part to fit requirements later) by changing project symbols. Leave the schematics alone. Like changing include files in software. I was thinking more of the situation where you have a published circuit and want to capture it and build it on a board. In this case you're probably not starting with gEDA stuff, and the pain of building the thing on a board is mostly the (effectively heavy) symbol creation.

This problem exists even in the big $$ commercial EDA tools. Symbol libraries simply don't work the way you wish they would. Too many possibilities... One company I worked for had a separate symbol for every single part. It was a 1-1 between schematic symbol and physical device. This meant that you could have multiple 10k resistors, even multiple 10k 0.1W 0805 resistors if the part was sourced from a few different manufacturers and ended up recorded as such in our CML. The actual process of creating such parts was not too arduous as it was usually a case of copy a similar part and change the necessary attributes. This was using Altium as the end to end EDA. It is interesting to note that despite an expensive, highly integrated schematic capture, parts library and pcb layout software that the same issues of component/symbol replication and redundancy exist. Although despite the proliferation of symbols in this case it did actually work ok. There isn't a magic bullet that will fix these issues. By having as much as possible light symbols that are easily modified, a public repository of customised heavier symbols this provides people with options. Perhaps in the hobby market having a set of predifined heavy symbols would be attractive however this really only suits those people who for whatever reason are not inclined to thoroughly check the symbol against their component and intended application. In these cases an 0805 resistor has no variants. This however is not the case for a design that goes through many iterations or has a particularly stringent set of design rules. Symbols need to be customised. Often on a project by project basis. All that can be done is to make this process easier where possible. regards, Geoff ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

I've had pretty good luck hand soldering leadless ceramic oscillators whose pins look a lot like those on QFNs. Make sure the pads extend far enough beyond the body to allow good contact with the iron, use lots of flux and it should be fine. Main problem would be soldering to the central ground/thermal pad that most QFNs have though. That might require reflow, but a hotplate might work OK for that.
