Instantiating a Step Multiple Times¶
You can clone a Step 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 step (i.e., GDS merge) instantiated twice and two nodes feeding different inputs to each (i.e., foo-gds and bar-gds):
You can use
Step.clone to build this graph:
# This is the default step gdsmerge = Step( 'mentor-calibre-gdsmerge', default=True ) # Clone the step 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 steps to the graph g.add_step( gdsmerge_for_foo ) g.add_step( gdsmerge_for_bar ) # Connect up both steps g.connect_by_name( foo_gds, gdsmerge_for_foo ) g.connect_by_name( bar_gds, gdsmerge_for_bar )
