Editing an Open Internal Circuit
A number of issues arise if you have used the same subcircuit device type
multiple times in a design and you open one copy for editing (i.e., by using
the Push Into command or by double–clicking on the device). You should
note the following points:
 The Schematic tool creates a separate, temporary type definition for the
open device when it is opened. Any simulation values that you view or
change, or any circuit changes that you make, will apply only to that
one device instance while it remains open.
 When you close an open internal circuit, the action taken depends on
edits that have taken place. If you have made any edits (such as any
graphical or structural change to the circuit) then all instance data (such
as signal values, and so on) from other devices of the same type will be
lost. It will be completely replaced by the values from the edited block.
