Circuit design/simulation software?
Charlie1138:
That sounds like an awsome idea, Gopher. You should do it. Definitely.
Gopher:
Thanks; I've got a way to go before I decide whether to implement any of this or not. I've got lots of grand, impractical visions of what it ultimately could be that would take me 10 years working full time to implement, but I'm forcing myself to reduce it to a minimum useful feature set; the idea of doing a stand-alone circuit testing app came out of this process. It is a subset of the core code for the final application which might be independently useful. If there's even a small market, I could make some money selling it as shareware, so I may pursue it even if I ultimately reject the 3d simulator idea. I'm working on a detailed design document now, so I can do a thorough task breakdown and estimate the total man-hours it would require. I'm also researching the existing market, which may be overcrowded already but seems to be relatively empty.

I primarily use multisim for basic designs. I use Xilinx which has a free ISE development for digital design and testing. you can also download modelsim which lets you simulate your design with test waveforms. Xilinx also can do VHDL design and synthesis.

SPICE I believe is the most popular circuit simulator software out there. There are many many versions, most listed on that link.
As for Eagle, yea its too overcomplicated for hobbyists . . . good only if you want to manufacture a board. I wasnt happy with its components library so I stopped using it the same day I started . . .
Anyone know good circuit drawing software? Just one level above paint, I mean . . . :P
Gopher:
Thanks for all the links; I'll have to research all of those. SPICE in particurlar, because it's core is open-source; it seems to be far more high-end than I had intended to implement myself, but if building my tools around it's core simulation is easier than developing a simpler one from scratch then it's logically what I should do. Whether it's easier or not depends on how SPICE is implemented.
Admin: Not that I know of, but it might actually be a nice way for me to break the circuit simulator down into two phases, make just a drag-and-drop circuit layout system first, so I'm glad you asked :) Taken by itself, it's a nice, manageable project.
