Compilation Errors for UVM constructs using xcelium

Hi,

I will shortyly tell the problem:

The following code line :

if(!$cast(tmp,rhs))
`uvm_fatal(get_type_name().toupper(), "Type mismatch")
                                                                                |

Generates two different errors at compile time :

*E,FCBLTIN ... built-in method call following a function call is not generally supported.
*E,NOTFXX ... Expecting a function name [10.3.3(IEEE)].

I cannot find out why this is not working.

Thanks in advance for the help,

Luca
