Inheriting an enum from a RTSC interface [message #519483]

Is it possible to declare an enumeration in a RTSC interface, then use that enumeration as a data type in modules that inherit it? Here's what I'm trying to do:

metaonly interface IBlock
{
    // data type enum (must match similar enum in header template)
    enum DataType {
        DATA_Float32 = 0,
        DATA_Float64,
        DATA_Int8,
        // snip
    };

    // snip
}

metaonly module MyBlock inherits IBlock
{
    override config IBlock.DataType allowed_input_types[] = [IBlock.DATA_Int8];

    // snip
}

Unfortunately, I get an error message when I try to build the MyBlock module:

Quote:

"MyBlock.xdc", line X: can't resolve name (IBlock.DataType)

I'm not sure what's gone wrong here. This seems like something that should be possible; I hope I'm just making some trivial error. I'd really appreciate it if anyone can help.

Joe,
You can use datatypes defined in other modules/interfaces.
I think you are seeing the error shown below because you are not referring to the scoped name of IBlock. Use the 'import' statement in your module to import the 'IBlock' definitions.

For example if IBlock is defined in a package called 'myPkg'
the module definition will look something like this:

import myPkg.IBlock;

metaonly module MyBlock inherits IBlock
{
config IBlock.DataType allowed_input_types[];

}
