Software simulation

akis · 27th November 2010, 06:21 PM

I have been usimng a simulation software to help me design my circuits. I like it because the user interface is excellent, allows you to place, connect and move components very easily and has a very good library of all sorts of components including for exampe potentiometers and variable capacitors, switches etc. It has an "interactive" simulation where you can interact with those components and in addition it has "tools" like probes, oscilloscopes, function generators and so on, so it really feels like a lab.

The problem I have been having with it is that very often I keep getting "convergence" errors - and the solution to this is to remove a few components, or change the interactive simulation settings a bit. But in the end I spend more time tinkering to make the simulation work, rather than the circuit.

Do you know of any interactive simulation software you could recommend?

Which tool are you using currently ? I have used Orcad Pspice and Protues ISIS as a part of my job . both are pretty good at its place.

free Ltspice is reputed to have very good convergence - it however has fewer gadgets/features - very much tuned to the working engineer
