Where can I get information on locking all the macrocells through SDC file? The constraint editor document I have is talking about doing it through pin planner but like to do it through constraint SDC text file.
The best method for doing this is to use a block-based design flow where you divide your design into design partitions and then "lock down" each partition as you complete its optimization. See the block-based design flow user guide:
I assume locking signal to microcell is probably feature like logic lock region and design partition in Quartus. You can preserve logic there are few method like logic lock, design partition post fit and back annotate. May refer to link below for details
