Hello friends and moderators, i urgently need a freeware for circuit simulation.I've searched the net a lot, but found that most were only free- trial versions or 'to be paid ' ones.At last i tried trial version of TINA-TI 9.0, but found it unsatisfactory-the transient analysis would never work.
Next i used LT-Spice IV, but found it too technical,i.e one has to learn special 'codes' to input spice directive, to modify components.
So ,,,,,please provide any idea, as i'm in urgent need of it,
please note that i want a user-friendly 'offline ' version ...

I think you should put in the time to learn LT-Spice. It is a very good simulator with lots of tutorials to show how to use it.


Here are a few:

LTspice is not as user friendly as some of the non-free versions of Spice but it is probably the best free simulator available and worth the effort to learn the syntax.

Have you looked at Simetrix? Their free simulator has some circuit size limits and I don't know how easy it is to use compared to LTspice.

 

Here is a list of circuit simulation software.

 

TINA-TI is really good choice.
