You need to find where you have specified "Fix_16_13" and correct the syntax. The string "Fix_16_13" is not a valid Simulink data type specification. If this string is intended to be a Simulink data type string, it should be fixdt(0,16,13) if unsigned, and fixdt(1,16,13) if the type is a signed type.

But i am using Xilinx Blockset Of Cordic SinCos and its output is intended to be Fix_16_13. Can you please tell me how can i change that to your suggested one in the block. Because there i only get to enter the input width 16 and binary point position 13. The output is predefined by the block itself.
