That's what managed to find:
1) Qucs qucs.sourceforge.net/
is a universal emulator circuits. On the site there are builds for Windows/Linux/Mac OS. There is also a screenshots. Like and support of semiconductor elements.Open source.
2) Electronics Workbench — also a program to simulate electronic circuits. As I understand it, a paid program, so a direct link could not give.
I hope these programs will help you in this interesting case.
