Hello everyone,
I am a Computer Engineering student. As part of course work I have to
participate in several electronics lab which deals with analog and
digital circuitry. Now I need a simulation environment where I can
simulate the lab experiments

I would be glad if any one suggest me a good circuit simulating
software.

Thank You
