IP Product: DDR3 SDRAM Controller supporting ALTMEMPHY

Warning: Ignored assignment: set_false_path -from [get_pins -compatibility_mode {*_alt_mem_phy_inst|*mmc|mimic_done_out*}] -to [get_keepers {*_alt_mem_phy_inst|*seq_wrapper|*seq_inst|*dgrb|*v_mmc_seq_done_1r}]

Description

This warning may be seen in the Quartus® II software version 9.1 SP1 when your design instantiates DDR3 High Performance Controller MegaCore® with leveling. You can safely ignore this warning because this constraint is for DDR3 High Performance Controller MegaCore without leveling.

This problem is scheduled to be fixed in a future release of the Quartus II software.
