All damping schemes implemented in MINIMOS-NT have in common that they damp the
solution vector by a damping factor d and hence obtain the following new
x* = xk + d . xk + 1 - xk
to replace the undamped new solution
xk + 1. The computation of the
damping factor d depends on the damping scheme selected. Investigations were
made on several damping schemes and potential damping was found to deliver
most reliable results .
d = with 0
being an adjustable parameter of the damping scheme,
the update norm of the potential sub-vector, and VT the thermal voltage. A larger
results in more logarithm-like damping of the updates.
