Use the graph stamp location constraint when the same graph has multiple instances that can be constrained to the same geometry in AI Engine. There are two main advantages of using this constraint:
- If you instantiate the graph multiple times, the throughput is the same. Because of the differences in routing, throughput might not be the exactly identical. However, it is much closer when using stamping.
- The runtime required is significantly less because the AI Engine compiler only solves a reference graph instead of the entire design.
By default, the Specify Graph Stamp option is deselected. When you select it, Model Composer lets you choose the graph from the drop-down menu where the graph on the left can be stamped.

Note: When you copy an AI Engine block, the constraints applied on the
original block might not properly copy.
