How to simulate initial condition for post-layout simulation?

BaaB

I am wondering how would you simulate initial condition for ring oscillator for post-layout simulation?

For schematic, from ADE choose Simulation --> Convergence Aids --> Initial Condition and I can set a node to a particular voltage.

However, is there a way to do that for post-layout simulation?

Thank you.

  • You can either still descend into the schematic, and hopefully the node will still exist in the extracted view - it would then be one of the nodes on the RC network. Or you can descend into the extracted view and click on the part of the net that you want to set the initial condition on (there needs to be a target on the layout side) or you could click on the node in the navigator (you need to be using a recent IC616 hotfix for this, if my memory is correct).

    So essentially it's the same for pre and post layout...

    Andrew.
