Note the following important settings:
- Incremental Synthesis selection box
- Use the Browse button to indicate if incremental
synthesis uses a known checkpoint, the last checkpoint created (default), or if
incremental synthesis is disabled.
- incremental_mode Synth Design option
- Describes how aggressive synthesis is with optimizations across partitions. The values are quick, default, aggressive, and off. Quick turns off most optimizations, aggressive turns on more and repeat synthesis on certain sections. Off tells synthesis not to use the incremental synthesis information in the DCP file.
