 ## *Baseline Macro Placement Generated by Human*
 The screenshot of the design using Cadence tool for standard cell placement and routing on Nangate45 enablement is shown below   
 <img src="./screenshots/manual_ariane133_Innovus.png" alt="ariane133_cadence" width="400"/>  
+The manual macro placement is provided in [manual_floorplan.def](https://github.com/TILOS-AI-Institute/MacroPlacement/blob/main/Flows/NanGate45/ariane133/def/manual_floorplan.def).
+We generate the manual macro placement in two steps:  
+(1) we call the [gridding](https://github.com/TILOS-AI-Institute/MacroPlacement/tree/main/CodeElements/Gridding) scripts to generate grid cells (27 x 27 in our case); (2) we manually place macros on the center of grid cells.
+
+The macro placement can a competitive baseline for [Circuit Training](https://github.com/google-research/circuit_training).
+The metrics after different physical design stages are shown below.
