download yenka (just google it) itis free for home use and allows you to build and simulate circuits on screen, it also allows you to export into another part of the program (real pcb) to create a mask for pcb etching or output to a cnc for pcb manufacture. It works with analogue, digital circuits as well as pic programming and simulation.
hope this helps

What you want is simulator. CircuitLab is a great start but only runs your schematic. It won't let you lay our a circuit board and test that. So once you get your schematic worked out it will be up to your to get the circuit board laid out and connected properly.

But there is a solution for that as well. It means doing twice the work but it can help to prevent errors. Once you have a working schematic from CircuitLab you can recreate that scematic in Fritzing. A free and open source program that helps you design a circuit and PCB. For all i know there may even be a way to import the schematic. You can lay out your components on a virtual breadboard, refine the schematic and then arrange the layout of everything on a PCB. You can take your working schematic, rebuild it in Fritzing and then work your PCB layout from there. In the PCB view you will see all your components and virtual lines connecting all the leads to help you keep track of what connects where. Once you have the parts laid out on the board as you wish you can use the auto rout tool to lay out the traces for you. It isn't the best tool four routing traces but it can be a good start. Often times you can find better routs for traces on your own. I've found if it can't rout some things or has to use a jumper then you need to rearrange the components so all the traces will work out better.

what are you checking your circuits for? and what kind of circuits?

Printed circuit boards. And to check if they work. sorry for not writing that
