STA中的post-map和post-fit

You can either perform Analysis and Synthesis to create a post-map database, or perform a full compilation to create a post-fit database. Creating a post-map database is faster than a post-fit database, and is sufficient for creating initial timing constraints. The type of database you create determines the type of timing netlist generated by the TimeQuest analyzer; a post-map netlist if you perform Analysis and Synthesis or a post-fit netlist if you perform a full compilation.
