I want to design some circuits of my own. My area of expertise is in Computer Science Engineering. I have listed out the components which are essential in the circuit. I want a software which can be used to design and simulate circuits for real time projects. Please suggest me the best among them. Thank you.
I usually use LTspice, which uses the same physical models as the alternatives listed by Chuck. LTSpice models can be directly imported to Eagle, which is somehow state of the art programm to PCB-design.
