Syntax add_to_collection [-h | -help] [-long_help] <collection_obj_1> <collection_obj_2>
Arguments -h | -help Short help
-long_help Long help with examples and possible return values
<collection_obj_1> First object collection
<collection_obj_2> Second object collection
This command takes two collections and returns a new
collection that is a union of the two. The second
collection is allowed to be a string, whereas the
first has to be previously-created collection, either
by passing any of the "get_" functions directly, or by
passing a variable that contains a collection (see code 
examples for this command). If a collection is used 
for the second argument, the types in the second 
collection must be the same as or a subset of the types 
in the first collection.

If the first collection consists of keepers, the second 
collection can only consist of keepers, registers or ports. 
If the first collection consists of partitions, the second 
collection can only consist of partitions or cells. If 
the first collection consists of nodes, the second collection 
can only consist of nodes, keepers, registers, ports, pins, 
nets or combinational nodes.
Example Usage
set kprs1 [get_keepers b*]
set regs1 [get_registers a*]

set regs_union [add_to_collection $kprs1 $regs1]

set regs_union [add_to_collection [get_keepers b*] $regs1]

#or even:
set regs_union [add_to_collection $kprs1 a*]

# - note that the last statement will actually add all keepers with name a*
#   not only registers! (will add IOs with name a*, if any)

# Get the first 100 nodes in the collection.
query_collection $regs_union -limit 100
