You cant just build up the circuit, see if it works and then worry about what to to next if it doesnt.
I mean, you probably do some calculations whether on a piece of paper or using a simulator software, before you build the circuit up and test it.
If you dont have much experience, that you can find yourself waisting lots of time on soldering and placing components on breadboard, when you could know before that it wouldnt work.

I use the sim. to experiment as being quite new to the world of electronics I've had many projects inside my head without any idea of what components I need to use to get these projects up and running.It's very easy to say go straight for the components and the breadboard or soldering iron if you have some experience of how components work and act together.
I for one have sat hours and hours just experimenting in simulation this does save me purchasing unnessacry components or even blowing them up !! oh and is quite enjoyable
Even some of the most experianced people use sims in one form or another!!!
Simulators do however tend to be sporadic in there simulation capabilities which can lead to even more confusion but in the most for me they have been a valuable tool.
Maybe in a few years when my knowledge grows my sim will become redundant but for now they work for me!!!

I think the phrase "garbage in, garbage out" applies here. If you don't have a good idea of whether the circuit even works or not, a simulator is not going to help you out. Simulators are supposed to verify functionality, not test it.
I strongly disagree. I use simulation extensively. I used to do VLSI design, and you cannot create a design with hundreds of thousands of transistors without extensive simulation.
Simulation is great for testing feasibility of a design before building it. You can start out simulating only idealized components. If you can make the circuit do what you want it to do in a highly abstract form, you can then keep adding more non-ideal behavior (parasitics) to see how that effects the circuit.
Simulation doesn't just apply to the electronics part of a design; you can model the behavior of physical systems, too. It is also great in optimizing a system because you can vary so many parameters at a time.
Getting a concept turned into a functional schematic is made easier because you have to go through the exercise of creating a circuit topology that the simulator will accept.
Simulation makes it possible to display all voltages, currents, power dissipated in components that would take hours to measure in an actual circuit. In the case of VLSI, there is no way to probe the innards of a complex circuit, the only way you can observe the internal nodes is using simulation.
btw-simulation is a great teaching tool. You can demonstrate behavior of circuits to a large group using a computer coupled to a projection system.
If you don't have a good idea of whether the circuit even works or not, a simulator is not going to help you out. Simulators are supposed to verify functionality, not test it.
Dear Eric
I have installed LTspice software in my pc computer.but I don't know hou to use it,would you like to give me some indication or show me some good books about the using of this simulation software.Thanks in advance.
