That would be a good place to be in, I miss the ability to get schematics for TVs etc.. and browsing the service manual for a 'scope out of interest for how it works. (I was amazed to see that my brother bought a Phillips LCD TV, and it actually came with a schematic though!) I'll chat to my colleges here who use PSpice for all their simulations, and find out what it is (if anything) which keeps them using it rather than anything else. I suspect, that in some cases, it is the ability to reproduce and use work which others have done using the PSpice specific models or extensions to the language. (As a non-PSpice user, I don't know what those are exactly, but I know I've found difficulty using SPICE code / models from the net with ngspice in the past). I have spoken to an academic here who has used PSpice (and other spices) since before PSpice had a GUI, and he maintains that PSpice has the _best_ solver of all the packages available. I strongly suggested he look at gnucap - and will try and push him that way again. Working with power-electronics, I suspect that gnucap might actually have some advantage for him, especially in dealing with simulations of switching converters. > Is software you can't study proper software for education? > > I go a step farther ... is equipment you can't study proper > equipment for education? As an engineer (and student), I am always curious as to how things work, but a long time ago resigned myself to the fact I'm never going to understand every detail of how everything around me was designed. What I will say, is that having knowledge of the _principles_, (and thus the limitations) of equipment is an absolute MUST, especially as things like digital oscilloscopes can mislead you if you're not wary. I hope that you get gEDA + gnucap used in your University. I'm fighting the fight here, even if it is just by using them myself, and when I can, by working on the code to allow more easy integration between the tools. Whilst I agree with John's comments that education shouldn't rely on wrapping up the inner workings of software, nor do I think that gEDA should dumb down, I do feel that a key requirement in _teaching_ is that the software should not get in the way of the underlying lesson. Sadly, most students are not comfortable with Unix and command lines. If providing a more familiar GUI approach to using the tools is possible, and doesn't detract from the core flexibility which benefits gEDA, I'm all for it. It will help us compete with commercial tools - which (IMHO) are not that good in terms of usability anyway.
