Backwards Time Simulation to Determine Boundaries of Convergence

mstrong5

Is it possible to run a backwards time simulation in Virtuoso 6.1.7?

I am trying to find out how far from an equilibrium I can set the initial conditions of a circuit's nodes and still have them converge to that equilibrium.  After the simulator solves a set of differential equations for a set of initial values, I want to trace the path of the points as they move backwards in time so that they diverge from the equilibrium instead of converging.  Is there a way I can set up ADE or another simulator get this data?

To be clear, I don't want to simulate what happened in the circuit's past while it was operating in a steady state.  I'm looking for conditions that may cause a circuit to have start-up issues.

    I'm not aware of any simulator that provides this capability. I'm not even sure that it would achieve what you're asking for even if it were available.

    Regards,

    Andrew.
