thus allowing RL to train within reasonable runtimes. Gridding enables hard macros to find locations consistent with high solution quality,
while allowing soft macros (standard-cell clusters) to also find good locations.
-[Grouping](./CodeElements/Grouping/) ensures that closely-related logic is kept close to hard macros and to clumps of IOs. The clumps of IOs are induced by IO locations with respect to the row and column coordinates in the gridded layout canvas.
-[Hypergraph clustering](./CodeElements/Clustering/) clusters millions of standard cells into a few thousand clusters. In Circuit Training, the purpose of clustering is to generate an approximate but fast standard cell placement that facilitates policy networks.
