When I analyze a VHDL design, the following warning occurs:
"Warning:Xst:2594 <attribute_name> on <entity/component/instance> in <XCF> overrides <generic/parameter on entity/component/instance>. Generic/parameter is ignored"
This error 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 ignored. The best way to work around this issue is to avoid the synthesis attributes and only use the generics or parameters.
