Hi Albert,

In the .map.rpt file you have attached, there are two error messages:

Error (12006): Node instance "U0" instantiates undefined entity "BRAM_16x1S" File: J:/altera/13.1/bram_16x2.vhd Line: 46

Error (12006): Node instance "U1" instantiates undefined entity "BRAM_16x1S" File: J:/altera/13.1/bram_16x2.vhd Line: 49

The error indicates that the BRAM_16x1S HDL file is not added to the Project. I compile the qar file, there is no BRAM_16x1S file in the project directory. Can you check if you have add this file to the project? You may check from the Project Navigator.

Thanks.

Best regards,

KhaiY
