Adding Drivers and Loads into the Logical Cone

For objects such as Ports, Nets, and Instances, the drivers or loads of these design objects, when selected, can be added to the logical cone. The driver or load of design objects can be added across multiple logical levels. That means the driver of a driver (two logical level) or the load of a load (two logical levels) can be added to the logical cone. At the expense of some runtime penalty for large designs, up to a maximum of ten logical levels of a selected design object can be added to the logical cone.

Note: To go beyond three Logic Levels, click the ellipse (...) and specify the number of logic levels, up to a maximum of 10, in the dialog box.
