ID:20947 Optimal time borrowing values have not been computed for this design. Timing results may be suboptimal (pessimistic). You can run 'update_timing_netlist -recompute_borrow' to compute optimal time borrowing values or 'update_timing_netlist -dynamic_borrow' to use time borrowing values correct for your current clock frequencies.

CAUSE: Optimal time borrowing values have not been computed for this design. This typically happens if you are using a design snapshot other than the Final snapshot, or if the time borrowing optimization step failed to run in Finalize for any reason.

ACTION: Recompute optimal time borrowing amounts by using 'update_timing_netlist -recompute_borrow' command. Alternatively, use the 'update_timing_netlist -dynamic_borrow' command to calculate time borrowing values that would be correct for your current clock frequencies.
