2. Design Flows Using Incremental Compilation

the standard incremental compilation flow

　　partitions can be compiled and optimized together in one Quartus II project

　　all design logic is compiled with a consistent set of assignments

　　perform global placement and routing optimizations

　　easier to ensure good quality of results

the team-based incremental compilation flow

　　accessing the top-level project from a shared source control system or creating copies of the top-level Quartus II project framework

　　developing partitions in completely separate Quartus II projects can be more challenging

combine design flows

2.1　　Project Management in Team-Based Design Flows

Design partition scripts automate the process of transferring top-level design information to partitions developed in separate Quartus II projects in a team-based incremental compilation design. Using the Quartus II software to generate design partition scripts eliminates the chance of error when communicating between the project lead and partition designers in a team-based design flow.

0-　　first perform a full compilation of top-level design
　　　　The top-level design can have empty partitions, can perform an Early Timing Estimation instead of a full compilation

1-　　On the Project menu, click Generate Design Partition Scripts.
