4060 simulation probs?

Hi All,

I've tried setting up a 4060 chip with std RC osc as per the data sheet - but when I run the sim nothing happens - ie no oscillation!

Can anyone else verify if it works?

I have checked GND & Supply connections and rest of my circuit inc PICAXE works - just no osc from the 4060 and hence no pulses from its outputs!

Generally speaking, you need to remember that in a simulation the situation is ideal - so capacitors will charge at the same rate etc. This can mean that there is nothing to 'kick' an oscillation. Suggest you look at initial conditions section of the help - you can specify an initial voltage for a net (IC=) or an initial charge for a capacitor (PRECHARGE=).

This is of course a complete guess and could be manure in your case - it would be useful to see the design/source if you are still having problems.
