[755-1] SDL

[Konstantinos Dovrolis <dovrolis@cs.wisc.edu>]

Folks,

When you create layout with SDL you actually don't see the following
layers in the transistors:
a. Select layers
b. N-well (for pMOS devices)
c. Contacts to active

This does NOT mean that these layers do not physically exist,
or that you have to add them manually. The SDL-generated transistors
inlcude all these layers by construction. What is shown in the
layout as an SDL-transistor is not the shapes that correspond to
the *physical* layers, but a *logical* representation of nMOS and pMOS
devices.
