555 TIMER as Astable Multivibrator.
------------------------------------
 You can Take 555 TIMER as a component besides the old ones to make your project with.
--------------------------------------
           Control the frequency by this formula

             1.44
f = --------------------------     
         (R1+R2) ×C

--------------------------------------
           Control the duty cycle by this formula

                            R1
Duty cycle = -------------- ×(100% )
                         R1+R2

---------------------------------------
For those who try to do it and did not success because of ""can not solve "" message 

You must do the following to work :

1- the program need the intial condition to make control so cut the outside component of 555 timer by switch and start the smulation without closing it to set the intial conditions .. and then close it and your  555 timer will work.

2- Decrease the simulation time . To allow your CPU to execute without lagging

Yes, this is the standard way we have hunderts of here. However, it seems to me a little overengineered. Anyway, to be correct your output is not corret. Its one inverter to much!
