We have extended the experiment of [Question 3](#Question3) to check the quality of our testcases. As mentioned [here](#Question3), we take the CT generated macro placement and then randomly swap the same size macros. We use the [shuffle_macro.tcl](https://github.com/TILOS-AI-Institute/MacroPlacement/blob/651a36626dd778018c5cf867b419e44f64fb103e/Flows/util/shuffle_macro.tcl#L29) script for this experiment. The following sections provide the details of macro shuffling experiments for different testcases.

The following items provide details of the macro shuffling experiments for different testcases.
- **Ariane:**
The target clock period of the shuffling experiment for Ariane133-NG45-68% shown [here](#Question3) is 4ns, which is very relaxed (See [here](#September18) for clock period sweep results). So we ran the same macro shuffling experiment for a tighter target clock period 1.3ns. The following table shows the preCTS / postPlaceOpt and postRouteOpt metrics. We shuffled the macros using six different seeds where seed values are 111, 222, 333, 444, 555 and 666.

- For the shuffled designs, the total power increases by 1.4%, the wirelength increases by 16%, and the runtime increases by 9% on average.

- **BlackParrot (Quad-Core):**
We have done similar macro shuffling experiment for BlackParrot (Quad-Core) design. The following table shows the preCTS / postPlaceOpt and postRouteOpt metrics. We shuffled the macros using six different seeds where seed values are 111, 222, 333, 444, 555 and 666.

We have tried a similar macro shuffling experiment for MemPool Group, but none of our runs completed.
