ID:24320 The -blackbox argument for the <Command name> command has been deprecated. Use set_max_delay constraints instead.

CAUSE: You used the deprecated set_input_delay -blackbox or set_output_delay -blackbox constraint.

ACTION: Remove the deprecated SDC constraint and set the appropriate set_max_delay constraint across your partition boundary. See https://www.intel.com/content/www/us/en/docs/programmable/683243/ for details.
