3.3. Incremental Compilation

Incremental compilation manages a design hierarchy for incremental design by allowing you to divide your design into multiple partitions. Incremental compilation ensures that the Quartus® Prime software resynthesizes only the updated partitions of your design during compilation, to reduce the compilation time and the runtime memory usage. The feature maintains node names during synthesis for all registered and combinational nodes in unchanged partitions. You can perform incremental synthesis by setting the netlist type for all design partitions to Post-Synthesis.

You can also preserve the placement and routing information for unchanged partitions. This feature allows you to preserve performance of unchanged blocks in your design and reduces the time required for placement and routing, which significantly reduces your design compilation time.
