DescriptionHierarchical Designs are challenging to plan and estimate while layout implementation specially when sub-cells layout views are not present throughout the hierarchy. Generate All From Source for top cell generates all hierarchical contents flat at top layout view, this becomes very challenging to floorplan and estimate the aspect ratio of sub-cells and top-cell, this way it adds lot of re-work and iterations to layout designer.

For designs that have unimplemented layout views existing at the top level and the levels below and where the schematic has a hierarchy and some or all levels of the schematic hierarchy have unimplemented layout views. Usually, for such designs, the placement at the top level is oblivious to the actual lower-level instances, so the top-level placement is often based on estimation. After the design is routed, there might be changes needed to the top level that are often expensive to accommodate.

With DPA, we can seamlessly implement both advanced and mature nodes, backed by real routing data. It uses the schematic hierarchy to create virtual hierarchy that can be realised, when appropriate. Blocks that have an existing layout in place and soft blocks, both are recognised by the DPA as valid inputs for planning.
