3Dblox: Unfolded view #9209
Description
Description
In the current 3DIC implementation in OpenROAD, ODB stores the folded (hierarchical) view of the 3DBlox design. However, correct visualization and downstream handling require an unfolded (flattened) view that resolves hierarchy transforms and produces geometry/connectivity in a single coordinate space.
Today, src/odb/src/3dblox/checker.* contains an incomplete unfolded representation that effectively unfolds chiplets only. We need to extend this into a well-defined class that represents the unfolded view of all relevant 3DBlox nodes. The current node types are:
- chiplets
- regions
- connections
- bumps
