1 - What are the default values for maxiters and maxsteps in the DC analysis convergence options for Spectre?
If I understand them correctly, maxiters is the maximum number of iterations of newton's method in solving for convergence. maxsteps is the maximum number of homotopic transformation steps in solving the problem.
2 - Will Spectre always take maxiters and maxsteps before reaching convergence? In other words, if the DC analysis does not converge, we are confident in saying the simulator has taken exactly maxiters steps in attempt to solve KCL using newton's method? Same idea for maxsteps...?
3 - Does the spectre simulator take a maximum of maxiters steps at each of the homotopic levels. For instance, doing 'source' homotopy, does the simulator take maxiters steps at each increment of the source voltages/currents? Can we say the simulator takes a maximum of maxiters*maxsteps calculation steps in solving the system? Or is this too naive to say..
Hope this makes sense, I appreciate any help! :D
