Layout Objects
Based on a powerful library of parameterized layout objects,
high-level circuits can be constructed from any combination of the following
topologies.
Note that each device is decribed with parameters like WIDTH and LENGTH as
well as a large selection of layout-related parameters like CONTACTS and
ORIENT; often more than 25 parameters are available for customizing each
object layout ...
