Description

When I analyze a VHDL design, the following warning occurs: 

"Warning:Xst:2592 <attribute_name> on <entity/component/instance> overrides <generic/parameter on entity/component/instance>. Attribute is ignored"

Solution

This warning occurs when there is a synthesis attribute that is different from the generic/parameter applied to the same instance. In this case, the generic or parameter is overriding the attribute and this is why the attribute is ignored.
