Description Due to a problem in the Quartus® II software version 12.0 SP2 and earlier, you may see these warnings during synthesis if your design contains dual-port memories. Warning (272007): MGL_INTERNAL_WARNING: ( The parameter value is not one of the pre-specified values in the value list.) altdpram|READ_DURING_WRITE_MODE_MIXED_PORTS The value assigned is CONSTRAINED_DONT_CARE and the valid value list is DONT_CARE|OLD_DATA|NEW_DATA The following warning may also be generated for these memories: Warning (287001): Assertion warning: MGL_INTERNAL_WARNING: ( The parameter value is not one of the pre-specified values in the value list.) altdpram|READ_DURING_WRITE_MODE_MIXED_PORTS The value assigned is CONSTRAINED_DONT_CARE and the valid value list is DONT_CARE|OLD_DATA|NEW_DATA Resolution These warnings can be safely ignored.
