    I have problem simulating this astable circuit. It never oscilates.

    What could be wrong?

    You need to put an initial condition on one of the node on the feedback loop. This question has been addressed several time in this forum. Do a post search for more information.

    You have a real hodge-podge of values in your circuit, resulting in some wierd RC time periods. No wonder it will not oscillate.

    Compare with the attached astable multivibrator circuit from Play-Hookey.

    @n9352527 : what's the word for searching such theme?

    @Eddy Kurent : I'm trying to do a different duty cycle.

    Try 'oscillator' and 'pspice' or 'spice'
