Re: gEDA-user: Silk text disappears when making a component
Elements do have silkscreen, though. I suppose you could use that to mark the top of the element with something. PCB could, in theory, explode any silk text into individual elementlines. Ugly but possible, with some coding. Or we could have someone add ElementText() to the file format ;-) ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user

I have a footprint for RJ45, but it can be used for connector with top or bottom contacts. I wanted to make two footprints each with an appropiate text, as I probably won't remember after making a board. I'll put the text on the board manually.

Actually, I'll probably just do a cut and paste job from the wiki for most questions on launchpad. I can also provide a link to the appropriate answer on the wiki. IMO, it's not a hassle at all. On the contrary -- it lowers the barrier to getting newbie questions answered, which is good for everybody. Thanks, Peter, for getting this set up!

Indeed, for symbols created by myself I do not use net attributes for power supply. I prefer to use visible power pins or to divide larger symbols into one separate power symbol. But there are some existing gschem-symbols with these net-attributes... OK, maybe I should make a local copy and remove the hidden nets.

Why not just remove the hidden nets from the symbols? With mulitple values of Vcc (or GND) the hidden nets create a lot of hidden problems. (* jcl *) P.S. I have a script that removes the hidden nets and generates appropriate power symbols. -- http://www.luciani.org ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
gEDA-user: gschem: How to overwrite invisible attributes?
Hello, there exists symbols with net attributes which are not visible/accessible when symbol is inserted in a schematic, for example net=Vcc:14 Problem: I am using many different positive supply voltages, i.e. 5V and 3.3V. I want that this symbol has 3.3V supply, but I have no Vcc defined (or maybe Vcc is defined to be +5V). Can I simple add a new attribute to the symbol to overwrite the invisible/hidden "net=Vcc:14" for pin 14 with something like "net= +3.3V:14" ? I think that I have read that this overwriting of attributes shall work -- but I can't find it again.

Those sounds good to me. As a general rule though, these are for your benefit. This said, SPICE or gnucap backends may attach meaning to the Device= attribute. In the existing symbols, see mostly: device=NPN_TRANSISTOR There is also device=SPICE-NPN (Note its "device" not "Device", similarly "description"). Also might be of interest, is the attribute: "documentation=" If you set the attribute to a URL, then you can access that URL in a web-browser from the menu "Hierarchy->Documentation" when you have a pacticular component selected. > My next problem is with the pins. I think what is most > important is that the pin numbers of the symbol pins > match the physical pin numbers of the particular > transistor when placed inside the PCB. Difficult with > TO92 as there are lots of em ;) Yes, a common problem. Also, rather surprisingly I can't find a TO92 package in PCB. My suggestion would be (if you're targeting PCB for board design), to find the right footprint in PCB and match your pinnumbers in your specific symbol. Al Davis or Start Brorson may be able to answer more about the requirements for using gnucap or some SPICE variant to simulate your design. You might take a look at: http://www.brorson.com/gEDA/ http://www.brorson.com/gEDA/SPICE/ > As you know... these small package transistors have > specific manufacturer numbered legs.

Can we attach any Leg # to any pinseq#? pinseq defines the output ordering for the spice backend. (And allows us to reference specific pins which might have different pinnumbers when using "slotted" components (e.g. one opamp symbol for all opamps in a chip with 2 or 4 inside). For SPICE, the order you _need_ pinseq incrementing is: collector (pinseq=1), base (pinseq=2) , emitter (pinseq=3). If you were modelling a transistor in an IC design, you could also hook up to the silicon substrate of the transistor with pinseq=4. > On the subject of pinnumber, what would a better > approach be?

You can do either, so long as the pin names in PCB match the pinnumber in gschem. pinnumber also works with letters - it just means that you'd be making specific PCB footprints for all the TO92 pinout variants you want to use. > On the subject of pintype for transistors, what should > I be using? pas?

Those values are only used by the design rule checker, and appear to be much more geared to digital logic - where there are clear power, input, output pins etc.. The purpose would be to check (for example) there aren't two outputs connected together, or inputs which aren't driven. > For pinlabel, would it be correct to say that I do not > need to include this attribute unless I am connecting > a particular transistor leg to another schematic > somewhere else?

I generally use them to show the signal names of signals on more complex chips. Eg. "IRQ" "D0" "A12", etc.. > Well guys... thank so much for your time going thru > this. Really appreciate it!

gEDA-user: Hello, Bills missing transistors and Attribute questions
Hi Everyone Thanks so much for looking! My names Mark and I am from Malaysia. Im a newbie and recent convert to the world of gEDA and have been really struggling trying to understand it all! I must have put in about 2 solid weeks of reading most of the gschem documentation. Slowly slowly I am figuring it out! I think one of the big problems is more that I am from a mechanical background and have little to non experience with EDA. Having said that, I really like the interface of gschem and hope to be able to get to use it well! Anyhows I am writing in to you all with the hope that some kind souls could help with a few things... The first thing is that when one looks thru Bill Wilson's really helpful gsch2pcb_Tutorial, there is a link to a library of transistor symbols and elements that Bill created. The URL is in the "Custom File Elements" section of the document: http://www.geda.seul.org/docs/current/tutorials/gsch2pcb/gsch2pcb-libs-20040110.tar.gz Unfortunately it leads to an object not found page. Would anyone have a copy of this library? This library is of particular interest to me as Bill discusses the problems of correlating all the various TO92 pin outs in gschem with PCB. My next question is about the Symbol Attributes. Lets say I wish to make a symbol for a BC550 transistor. As I would be using this particular device a lot, I would like to make this symbol as correctly as I can. So, if I have a BC550 NPN GENERAL PURPOSE TRANSISTOR, what are the preferred values to give: Device=? Description=? My guess is that: Device=NPN TRANSISTOR Description= BC550 NPN GENERAL PURPOSE TRANSISTOR Would this be correct or would you suggest some other values? My next problem is with the pins. I think what is most important is that the pin numbers of the symbol pins match the physical pin numbers of the particular transistor when placed inside the PCB. Difficult with TO92 as there are lots of em ;) As you know... these small package transistors have specific manufacturer numbered legs. In the case of my BC550, I have a Leg #1 (Collector), Leg #2 (Base) and Leg #3(Emitter). Does it matter say if pinseq=1 is where transistor Leg #2 goes? Can we attach any Leg # to any pinseq#? On the subject of pinnumber, what would a better approach be? Should I use values of 1, 2 and 3? Or would it be smarter to use values of E, B and C for my transistor symbol? On the subject of pintype for transistors, what should I be using? pas? I am uncertain how open collector and emmiter fit into the picture here. As I might wish to one day run spice... I would really appreciate some info on what values I should be setting for the E, B & C legs on my transistors. For pinlabel, would it be correct to say that I do not need to include this attribute unless I am connecting a particular transistor leg to another schematic somewhere else? Or do I need to include this attribute. If so.. what would I label them for the E, B & C legs on my transistors? Well guys... thank so much for your time going thru this. Really appreciate it!
