simulate oscillator

I made a Multivibrator circuit like below

**broken link removed**

How to simulate it in SPICE??

I simulate it by transient but it don't oscillate......

Please help me............
 

Hi
you must initialize one node of it.
see .ic command.
regards

you can take this.
 

Dear friend

Please double click on the capacitors and set initial conditions (ex: IC=0.2 volt) on them. Then run the simulation again.

Best wishes :D
 

and maybe you should make a long transient simulation because usually need a plenty of time to start the oscillation
 

u can set an initial condition for cap.
 

You can use initail condition to improve the simulation time, and you must run long time for oscillation , And check the stable issue
