Yes in part selection select spice directory and there are boxes for that. But I don't remember which attribute the command should be filled in. There should be comments with each symbol which would be displayed next to each symbol in symbol selection. The comment for these particular SPICE symbols should contain information what attribute the command should be filled in. For 7400-type symbols the comment should contain information whether the symbol is designed for hidden net or seventh gate power supply or whether the symbol is broken, obsolete etc. so people won't use broken or obsolete symbols which have to be there just for backward compatibility reasons for existing schematics. I am using gschem with gnucap and it's a bit pain in the ass - I have to run a hefty script to tweak the output. I don't know if it's case with SPICE too or not. But I think there should be also a gnucap backend. This is gEDA. Is SPICE part of gEDA? gnucap is definitely a part of geda if I am right. So why is there backend for SPICE and not gnucap? I am working on Ronja for already 7 years so I don't mind some ocassionally hefty script when the whole source is full of makefiles and scripts anyway, but I guess that other users who will not want to start their project by downloading 250MB Ronja source tree and tweaking schematics in the schematics/ directory will have severe depressions from these usability issues :) CL< > > The other method of course is to put these plotting commands in a > separate file, called foo.cmd, and copy them into ngspice whenever I > want to repeat a simulation. > > regards, > ->HS
