I am using simulink to create a serial adder using three universal registers. I keep getting the following errors: Function 'BITSLICEGET' is not defined for the first argument of class double.
Function 'HDL Operations/Bit Slice/bit_slice' (#60.47.89), line 4, column 5: "bitsliceget(cast_to_fi(u), lidx+1, ridx+1)" Launch diagnostic report. Component: MATLAB Function | Category: Coder error Errors occurred during parsing of MATLAB function 'HDL Operations/Bit Slice/bit_slice' Component: MATLAB Function | Category: Coder error Errors occurred during parsing of MATLAB function 'HDL Operations/Bit Slice/bit_slice' Component: Simulink | Category: Block error Any help would be great. Thanks

bitsliceget is supported for fixed point types only. What is the type of the data that you are supplying as input to the bit slice block?

Any follow-up on this question?
I got the exact same error when I use the HDL coder. It seems cast_to_fi() is there to make sure that the input to bitsliceget() is an fixed point type.
