Hello All, Thanks for the advice. I'll give it a go. The device in mind is an Altera Cyclone-3 FPGA. Most probably the ep3c5. As for the function, it will do audio-dsp like functions. I2S in, 3 to 4 channel FIR filtering (1024-tap) and I2S out. When not filled completely i will try to add a

I found that Vdd got connected to Vcc sometime during the schematic entry. Short of poring over the entire schematic, how can I find where this happens? You can cut apart nets and rerun gnetlist if you must stay in graphical mode...errr no, there's no higlightin in gschem yet, so you

I am following the gnucap tutorial and am using the opamp-vf.ckt in the gnucap examples. I'm using the following commands: --- gnucap eg6.ckt gnuplot set data style lines plot 'eg6.dat' using 1:2, 'eg6.dat' using

I see three mistakes .. one is in the documentation, one yours, and one is something with the program that really should be changed. The documentation mistake ... You need to do -b for batch mode. Without -b it loads the file for interactive operation. $ gnucap opamp-vf.ckt should be .. $

Re: gEDA-user: PCB Element IDs

2008-02-03 Thread DJ Delorie
The text you refer to is called a refdes in PCB, not an element ID. Elements have internal IDs, so use refdes to avoid confusion. You might want to try a more recent PCB; this was a common problem a while back. In recent PCBs, there are settings to force the crosshair to ignore all text, or
