Of course I don't want that.

I didn't ask about a schematic editor to make pcb alyouts eventually.

I already have Eagle, Protel, and even Pcad. (though I use only Eagle being easy, do have time to learn others)

What I asked is an electronic circuit maker and simulator software.

Wherein you could make any circuit by selecting components from the library, for example make an astable oscillator from 555 and it will simulate. Make any digital circuit from basic gates give any signal at the input and it will tell you what's happening at every node.

I already Got it.

Microcode.com also offer a students version free, a cut down of there regular pack Circuitmaker 6.1

Its very nice.

Try it, its good for those who want to learn electronics.
