Quite frankly, your question is so very general that a concise yet complete answer is essentially impossible. One can take a four-year degree in engineering in college and still not have covered all that one might need to know in designing to satisfy the needs of any given application.
Also, personally, I don't much like the software I've seen so far intended for engineering purposes and I suggest that you devote your attention elsewhere. I much prefer to suggest that you embark on a study of math and of basic circuit theory.
You want as a minimum, a solid working grasp of algebra, geometry and trigonometry. You also will want calculus and differential equations. Later on, you'll need LaPlace transforms, Fourier analysis and more.
For circuit theory, you would begin with Ohm's Law, the properties of capacitive and inductive reactances, transformers (a deceptively complex area of study by the way when you REALLY get into it), Thevenin and Norton equivalent circuits, node analysis and loop analysis. (Whew!)
That is ONLY a beginning, mind you, but a very substantial one. Consider enrolling for courses. This is a whole lot to swallow one one's own and probably impossible to do properly without instruction.
