Instantiating a Node Multiple Times

You can clone a node in your construct.py and instantiate it multiple times in your graph.

For example, say you wanted a graph that looks like this, with the same node (i.e., GDS merge) instantiated twice and two nodes feeding different inputs to each (i.e., foo-gds and bar-gds):

You can use Node.clone to build this graph:

# This is the default node

gdsmerge = Node( 'mentor-calibre-gdsmerge', default=True )

# Clone the node however many times you need

gdsmerge_for_foo = gdsmerge.clone()
gdsmerge_for_bar = gdsmerge.clone()

# Give them both new names

gdsmerge_for_foo.set_name( 'gdsmerge-for-foo' )
gdsmerge_for_bar.set_name( 'gdsmerge-for-bar' )

# Add both nodes to the graph

g.add_node( gdsmerge_for_foo )
g.add_node( gdsmerge_for_bar )

# Connect up both nodes

g.connect_by_name( foo_gds, gdsmerge_for_foo )
g.connect_by_name( bar_gds, gdsmerge_for_bar )
