use
Specifies that the instance is an instance of the specified cell in
the specified logical library.
The following are examples of instance clauses:
instance top.dev1 liblist lib1 lib2;
This instance clause tells VCS to resolve instance top.dev1 with
the cells assigned to logical libraries lib1 and lib2;
instance top.dev1.gm1 use lib2.gizmult;
This instance clause tells VCS that top.dev1.gm1 is an instance of
the cell named gizmult in logical library lib2.
The cell Clause
A cell clause is similar to an instance clause except that it specifies
something about all instances of a cell definition instead of specifying
something about a particular instance. What it specifies depends on
the use of the liblist or use keywords:
liblist
Specifies the logical libraries to search to resolve all instances of
the cell.
use
The specified cell’s definition is in the specified library.
Hierarchical Configurations
A design can have more than one configuration. You can, for example,
define a configuration that specifies the source code you use in
