I'm having issues creating sub-circuits in the new update iCircuit 1.4 for Mac OSX.
I am able to do this without issues on my iPad/iPhone so I am aware of "how" to do it. No iCircuit file is selectable from the sub-circuit browse feature. I even tried creating a resistor with ports on both terminals just to confirm it wasn't my circuit. Is anyone else having this issue?

I'm having the same problem. All of the iCircuit files appear to be greyed out.

I even tried to create a .cir file on my iPad that contained a sub-circuit. That didn't work either.

Me Too. I have the same issue. All .cir-files are greyed out. Please fix immediately!

I have the same problem.

Please fix that problem!

Not to sound redundant but I am having the same issue. thx

same problem here :/ A quick fix would be nice.

Subcircuit is a great tool... when it works! So please Mr. Krueger, can we have fix! Thanks :)

Same issue, when is the fix for this coming out? I need this feature!

I need to use Subcircuit, but it doesn't works, please fix it quickly!!! I have to do my homework!!!

Oh, man, Frank added another new killer-feature to the app, except he forgot to tell users it doesn't work. LOL. :D

Frank, fix the simulation engine first before adding more advanced features like subcircuits. Subcircuits is of little use, if your engine can't handle a 2 transistor amplifier, because even if it gets convergence, performance sucks so much it is barely usable.

It is a shame to see this feature, especially, not working. iCircuit is an amazing concept and would be a bargain at twice the price if it actually worked correctly.

Yeah, the concept is excellent, but execution could be much better. The main problem is the author of iCircuit is *not* the author of the simulation engine behind it. He just ported some opensource Java code of pretty low quality to iOS and made a cool looking GUI. The engine is good as an educational project, but not a production quality simulator.

If someone did something with iCircuit GUI and SPICE-like powerful simulation engine, it would be really, really cool.

Has anyone else had trouble contacting Frank? Has everyone paid for this app? If so, how much. The version I purchased was $10. Not going to break the bank but the app should at least do what the write up claims, shouldn't it? Has anyone got subcircuits working? If so, how? Please post the solution if you have.

same here, subcircuits not working on mac os x!

The UI is broken (shaaaaame boooooh, bad engineer!), but I have been able to get this working by doing this:

- In your master circuit, add a subcircuit component, name it something recognisable like MyFavoriteSubcircuit
- Save both circuits, lets say /Users/myself/master.cir and /Users/myself/subcircuit.cir
- Close iCircuit and open master.cir in your favourite text editor
- Search for MyFavoriteSubcircuit, you should find a line with only numbers, followed by a line with your label, eg:


220 1152 320 1056 384 0
> MyFavoriteSubcircuit


- Now add a space and the path to your subcircuit file, in URL encoded format, to the line above, like so:


220 1152 320 1056 384 0 %2FUsers%2Fmyself%2Fsubcircuit.cir
> subcircuit


ps: I have no idea what I'm doing, that it worked for me doesn't mean it will work for you. You should backup everything all the time.

It works for me. Still, it looks like a simple fix (path issue, trivial), why the Author isn't pushing this?

Have the same problem. Looks long-standing. ???
