@defopt -T type
Instantiate one instance of type @var{type} as the top-level, 
ignoring all previous top-level instances in the object file.  
This variation @emph{does} recursively instantiate substructures.  
The ports of the instance of @var{type} (if any) will not be connected
to any other processes.  
This is particularly useful for selecting test structures
out of a collection of test structure definitions.
