For the life of me I can't seem to get my head around it, but then I might just be too tired. Can anyone point out what I'm missing? I open geda, create a sch file (circuit), and then run gnetlist -g spice-sdb . I then run ngspice (or gspiceui) but it comes up with errors over the 555 (U1) and diodes (d?) I'm running like this: Error on line 9 : d1 2 0 unknown unable to find definition of model unknown - default assumed Error on line 13 : u1 0 4 3 +9v 1 4 5 +9v unknown unable to find definition of model +9v - default assumed unknown parameter (4) Doing analysis at TEMP = 27.000000 and TNOM = 27.000000 CPU time since last call: 0.040 seconds.

There is nada on google about any of this - but I suspect it is missing model files or something, and before I go attaching to yet another mailing list, I thought I'd run it by here first as I'm sure there are some who use this and have experience with it on FreeBSD 9. TIA guys
