2.1.2. Compilation Hierarchy
For example, the dni database directory contains checkpoint directories pertaining to each of the Analysis and Elaboration stages, such as elaborated, instrumented, swept, and constrained, Similarly, the synthesized directory contains a snapshot of the Synthesis stage of the compilation.
If you use design partitions, such as in a block-based design, the Compiler also isolates the results for each design partition. The Compiler fully preserves routing and placement within a partition. Changes to other portions of the design hierarchy do not impact the partition.
This hierarchical structure allows you to optimize specific design elements without impacting placement and routing in other partitions. The hierarchical project structure also supports distributed work groups and compilation processing across multiple machines.
