Can L-Edit extract the vertical parasitic capacitance?
L-Edit, currently, does not have builtin vertical parasitic capacitance extraction. However, it can be accomplished by defining a derived layer that is the overlap of two layers. The coupling capacitance is calculated based on the layer-to-substrate capacitance value of this derived layer, which should be set to the layer-to-layer capacitance value. All capacitances in L-Edit are calculated with an area and a fringe term. Below is an example of how a M1 and M2 layer-to-layer parasitic capacitance can be extracted.
