ahkab.dc_guess¶
This module provides the get_dc_guess()
method, used to
compute a starting point to initialize a Newton-Rhapson solver.
Module reference¶

get_dc_guess
(circ, verbose=3)[source]¶ Build a DC guess from circuit inspection.
Notice that OP analysis will call this method on the users’ behalf if not instructed not to do so.
A element can suggest its guess through the
elem.dc_guess
field. If the field is not set, or not available, no information on the most likely biasing voltage is assumed.Parameters:
- circ : Circuit instance
- The circuit instance the guess is being computed for.
- verbose : int, optional
- The verbosity level (from 0 silent to 6 debug). Defaults to 3, medium verbosity.
Returns:
- dcg : ndarray or None
- The DC guess, in numpy array form, or
None
, if it was not possible to compute a meaningful guess.
