Hi Al, I'm trying to find a solution to how to set the initial condition for inner transient analysis. Correct me if I'm wrong but isn't it impossible to calculate the state-transition function Phi(v0, 0, T) and the jacobian of it Jphi with NA since the full-state of the circuit is not captured by the voltage vector. Using MNA the vector of node voltages and currents through inductors represents the state of the circuit.
It would be possible to probe the current of all inductors and then calculate the MNA matrix and LU-factor it for each timestep and then use that to calculate the state-transition Jacobian. But it would be a pity to not use the NA Jacobian. But I don't know how to handle this for spice-devices. Any ideas?
