As for the device equations global damping strategies have been used for
circuit equations. E.g., for JANAP [6] the damping scheme
after Bank and Rose has been used. In numerical experiments it was tried to
use global damping schemes for the fully coupled mixed-mode equation system.
As the non-linearities are so strong, the damping for the node voltages was
found to be so restrictive that they were only updated with a few milli-Volt
or less.
