RE: [sv-bc] Unclear text in associative array

It means that index_type may only be * or a type name (either a built-in type or a previously typedef'd name), and cannot be an anonymous type. For example, the following declarations would be illegal:

integer array1[ bit [2:0] ];
int array2[ struct packed { bit a; bit; b } ];

The way to declare such a type is:

                typedef bit [2:0] IndexT1;
                typedef [ struct packed { bit a; bit; b } IndexT2;

integer array1[ IndexT1 ];
int array2[ Index2 ];

Hi,
In section 7.8 of SV 2009 LRM, it is mentioned:

It shall be illegal for index_type to declare a type.

What is the meaning of this sentence? It will be better if an example is provided.
