Comments |
- Where are the source and sink ports defined?
Capacitance values can be extracted without assigning source and sink ports. It is only necessary
to specify the conductor nets.
- What results can be obtained from post processing?
Post processing output helps to understand the physical phenomena, by displaying the
distribution of the charge (ABS Q, Smooth Q).
