gEDA-user: chassis ground - symbol errors, I wonder?
Hello Fellows, I've added a chassis ground and used the symbol: chassis.sym but when I compile the schematic to using gnetlist: I get the following: "Missing Attributes (refdes and pin number) Missing Attributes (refdes and pin number) Missing Attributes (refdes and pin number) Missing Attributes (refdes and pin number) Missing Attributes (refdes and pin number) ... (snip)" when I check the output file, it reads: (snip) Found pins without the 'pintype' attribute: H4:1 H3:1 H2:1 H1:1 U?:? (snip) The H1-H4 are four mounting holes, but why only one "U?:?" and when I check my .net file I noticed this: harpy01C.net:unnamed_net40 U?-? J4-G harpy01C.net:unnamed_net29 U?-? J3-G harpy01C.net:unnamed_net26 U?-? J6-G harpy01C.net:unnamed_net25 U?-? J5-G harpy01C.net:unnamed_net24 U?-? J8-G harpy01C.net:unnamed_net23 U?-? J7-G harpy01C.net:unnamed_net14 U?-? J2-G harpy01C.net:unnamed_net3 U?-? J1-G These correspond to the Ground connect pins on my connector that are now connected to Chassis GND. I labeled the net "CGND" Have any of you come across this issue with chassis.sym? Any ideas that you folks might have to solve this will be greatly appreciated.

gEDA-user: TI hi-fi headphone amplifier symbol and footprint: thermal pad and unconnected pins raise error flags
The footprint for the Texas Instruments part: TPA6120A2 calls for a thermal pad and the bottom half of the pins to be connected to ground. A problem has risen with footprint, DRC errors highlight the pins in GEDAs pcb tool. I have configured the symbol and called for the rest of the pins to be connected to ground, but an error flag persists. What is the best way to troubleshoot this issue? The symbol has a property called: GND=6,7,8,9,10,11,12,13,15,21 My slotdefs are set: slotdef=1:1,2,3,4,5 and slotdef=2:20,19,18,17,16 So why does pcb highlight these pins when I connect them to GND? // Sal Aguinaga // Northwestern University ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
gEDA-user: add Logo to silkscreen in pcb, exactly how to insert the EPS?
What is the latest consensus on "how to add eps logo to silkscreen"? Back in Nov 2008, there were a few emails back and forth on adding a logo to the silkscreen.

gEDA-user: pcb drc checks before releasing pcb || cost diff. from vendor to vendor
Hello Fellow designers: I'm new to geda, I've designed my first board with gschem and pcb. First, do one of you have a check list of "must do" before releasing a board to a board fab house? I've used the DRC checks and I don't know if all are accurate or if all are needed. I've search the "seul.org" mail archives and there is a lot of info and didn't find a mention or such a list. If any of you have any advice regarding things I should check before I release the board to the fab house, please let me know. Lastly, I have a question about Sunstone (pcbexpress) board fab pricing vs Advanced Circuits'. I noticed that Sunstone quotes over a $100 more for a 2-layer, 4x9 inch board over the cost priced by Advanced Circuits ( and Imageneering inc). Do any of you have any info on why sunstone is so much more and is it worth the extra cost? // Sal Aguinaga // Northwestern University ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
gEDA-user: PCB | how to update the pcb, if a change is made to the schematic?
Hello Fellows, I am a new user of gschem and pcb. I have a question to which I have searched the archives, but come up empty handed. ** In the PCB, is there a command to move components to a specific x,y location? ** After starting on the PCB, I have to make a change to the schematics, is there a way to update the pcb file? Without affecting placement or All routing? If a email thread has covered this already, would you mind sending me that link. Thank you, I truly appreciate any help on this. === running gschem and pcb on Mac OS X === // Sal Aguinaga // Northwestern University ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
