gEDA-user: Multicomp Footprint SD/MMC slot
Hello List, I'm new to pcb and looking for an footprint for Multicomp SD/MMC Cardslot. First question is this the right place to ask for this ? This is the exact part type: Multicomp SDAMB-01215BT00 Details link: http://octopart.com/sdamb-01215bt00-multicomp-5438442 hopefully someone out there had a nice footprint :) thanxs a lot michael ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

Unfortunately, there is no connector named sdamp, yet. The data sheet does not give explicit recommendations on the land pattern. Good luck with rolling your own footprint!

While we're at it, was there a consensus on using verilog-ams as the format of choice for Al's translation system? Consensus? Not yet. Al does ask for two way translatable formats, so including enough info to recreate a schematic is implied, but not how exactly appearance matching it will be. I'm thinking of graphic elements as only the generic rectangular boxes at first, then by way of text attributes, add more later. the detailed info to recreate schematic appearance is not needed for effective translation purposes, just connectivity. A reasonable goal is to capture data that assists in putting back a schematic as it was, but not doing the layout part of a schematic. A big assist would be to keep any unique identifiers from schematic symbols until a symbol is changed for simulation purposes. Then one could relate the simulation netlist points to the original schematic points for cross probing, even when the sim netlist is a subset or different in part from the original. Then you could do a process of back annotating, deleting schematic symbols not found in the sim netlist, and saving the modified schematic as an aid to simulation displaying. With a small amount of symbol layout time, your new schematic for cross-probing purpose would be a one-to-one match with the simulation. Al asked for a format for electric/electronic netlists that can include any simulator's or schematic/netlist capture program's circuit information.

Can you compile a list of tasks that need to be accomplished before the topo router is ready for general use? The smaler the individual tasks, the more likely they can be tackled by low time hackers like me... For sure. It would require some careful consideration though.. I'll get back to you within a week. Keep me in the loop, too. bump the topic up... Since this thread started, I've discussed continuing work on the toporouter with my Uni supervisors. They are OK with me taking time off from my PhD if the GSoC thing goes ahead. I would prefer to do most of the core work myself, rather than try and get others to implement my 'half baked' and untested ideas.. The idea of getting someone to implement something that I'm not even sure of myself doesn't seem right.. As for smaller individual tasks.. I was thinking that an abstraction layer for the autorouters might be a good idea. We now have 1.5 autorouters (very soon to be 2x complete autorouters), and an abstraction layer would help future work built on top of the autorouters, such as the auto-plow feature Harry Eaton mentioned, seamlessly switch between the underlying autorouters.. An abstraction layer would also be a good first step towards untangling the toporouter from PCB, and making it more of a general open source autorouter. Another small task, which would *really* help me, would be an automated testing framework for the autorouters. I would like to have some tool which I could throw a directory of unrouted boards at, and for each board it comes back with images of the output from the toporouter the autorouter, as well as performance results (wiring length, runtime etc). Someone also suggested switching out the absolute wiring length metric with sum of each nets wiring length to MST length ratio.. That would be a good small task to familiarize oneself with the toporouter autorouter code.. and the results would be very interesting if that metric is also used as the cost function in the net ordering. btw, if there are other little projects or features you would like to add.. I'm happy to help in anyway I can, including being available on IM/IRC to answer questions.. Also, can anyone think of a new name for the toporouter? There is already a commercial tool called the 'toporouter', which I don't want us to be confused with.

Absolutely agree with you about fixing those show-stoppers first.. the problem is none of those issues (e.g., vias, existing geometry etc) are small tasks suitable for people new to the toporouter to take on. I would prefer to deal with those issues myself as part of the GSoC this year. That said, I can surely come up with loads of feature requests. All kinds of suggestions to the router, layers exclusively for specific signals, customizable preferred directions, design rules that depend on the net, ... ;-) Yup, those are the features I really want to get other people implementing, so I can spend my time working on core features like vias and existing traces..

Re: gEDA-user: Toporouter update?
Haha nice.. I used to route boards by hand, but then I became awesome instead. True story. tea - keyboard I suggest it because (1) it's awesome and (2) it's suggestive of 'autorouter. Back on topic now, we might get some good hints for future features from Toporouter (the commercial autorouter product). One of the ones that they tout is understanding logical equivalence of certain pins. You could further imagine a very advanced version of this that could select which slot of (say) a quad op-amp to use. But, let me also voice that I'm 100% behind getting the basics working first. I would *love* to be able to use this for even single sided boards, today. Adding in existing geometry is key. Vias would be great, too. :) Honestly, optimization beyond what's already there would be great for a future version, but I'm so craving just what I've seen so far. ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

I've already had a first stab at implementing that, in an effort to generate a good solution for DDR2-SDRAM - FPGA routing. It is very hard to do well, as the problem just gets even more NP-complete =) Since my first attempt year ago, I've learnt a few data mining/machine learning tricks, and I'm feeling much more confident about doing it *well* a second time around. btw, those toporouter guys are rather misleading with their results.. they show off pictures of boards which have been fixed up afterwards.. e.g., 20 mins of toporouter time, and 40 mins of hand editing for one of their boards. And while I'm on the subject of comparing autorouters.. I was looking at a Mentor license agreement the other day.. and I was shocked to see that they prohibit you from using it to compare results with other tools.. wtf..

That kind of partial route performance still enough to justify plenty of tool spending until layout is well automated. As in, not needing more than a day after netlist and footprints are verified to auto/hand route a 200 component board. And while I'm on the subject of comparing autorouters..

Since Harry Eaton has never been shy with lots of really good criticism and comments regarding the toporouter (off list), I asked if he would be interested a few weeks ago.. I hope Mentor or Cadence don't find out about you and make you an offer you can't refuse. I doubt we are even on their radar =) In any case, I'm still a student for the next while, which isn't going to change..
