[MacroPlacement](../../) is an open, transparent effort to provide a public, baseline implementation of [Google Brain’s Circuit Training](https://github.com/google-research/circuit_training)(Morpheus) deep RL-based placement method. In this repo, we aim to achieve the following.

We have extended the experiment of [Question 3](#Question3) to check the quality of our testcases. As mentioned earlier, we take the CT generated macro placement and then randomly swap the same size macros. While swapping the macros we update macro orientation based on the swapped macro orientation. The following sections provide the details of macro shuffling experiments for different testcases.

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.

-**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 increase by 1.4%, the wirelength increase by 16%, and the runtime increase by 9% on average.

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.
- For the shuffled designs, the total power increase by 6%, the wirelength increase by 33%, and the runtime increase by 16% on average.
