XST - "Warning:Xst:2595 or on in overrides . Old value for defparam is ignored"

Description

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

 

"Warning:Xst:2595 <defparam> or <attribute_name> on <entity/component/instance> in <XCF> overrides <generic/parameter on entity/component/instance>. Old value for defparam is ignored"

Solution

This error occurs when there is a synthesis attribute or defparam that is different from the generic/parameter applied to the same instance. In this case, the newer value for the defparam overrides the older one.
