The graph stamp location constraint can be used 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:
- When the same graph is instantiated multiple times, the throughput should be same. Because of the differences in routing, throughput might not be the exactly identical. However, it will be much closer when stamping is used.
- The run time required will be 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 enable this, Model Composer allows you to select the graph from the drop down menu for which the graph (in lhs) can be stamped.
