Error Assigning binary literal to ufixed

Hi guys,

I have been writing a ROM that I step through using a simple counter. Up until now the output of the ROM has been unsigned(9 downto 0), and assigning binary literals in the form "1111100000" has been working fine.

However I decided that I might want to try with unsigned fixed point with the same total width as in the unsigned case ie ufixed(7 downto -2). see attached file...

Now my understanding is that it shouldn't matter how the literals are assigned, so I haven't changed the literal values at all.

However I get the following errors:

Warning (12001): Port "oDAC_DATA[8]" does not exist in entity definition of "DDS_ROM". The port's range differs between the entity definition and its actual instantiation, "DDS_ROM:inst2".

Warning (12001): Port "oDAC_DATA[9]" does not exist in entity definition of "DDS_ROM". The port's range differs between the entity definition and its actual instantiation, "DDS_ROM:inst2".

Could someone please enlighten me as to where I may be going wrong please...

thank you
