This is my first attempt at gEDA, so please forgive my ignorance. I'm trying to model a Cockroft-Walton voltage multiplier (http://en.wikipedia.org/wiki/Cockcroft-Walton_generator) as a simple first test circuit. I had no problem using gschem to make the circuit schematic, but i run into problems with my ngSpice simulation. It tells me: Error on line 12 : d4 4 higherout unknown unable to find definition of model unknown - default assumed I get similar error message for all 4 diodes. The simulation results are unreasonable, so I don't think the "default" (what ever that my be) diode model is what I want. The output of #rpm -qa | grep geda is: geda-gattrib-20080127-2.fc8 geda-examples-20080127-1.fc8 geda-symbols-20080127-1.fc8 libgeda-20080127-1.fc8 geda-utils-20080127-1.fc8 geda-gnetlist-20080127-1.fc8 geda-gsymcheck-20080127-1.fc8 geda-gschem-20080127-2.fc8 geda-docs-20080127-1.fc8 I have attached my netlist and schematic file. Thanks to anyone who can tell me what I've done wrong!
