4.2.3. Using DSP Builder Advanced Blockset References

All the signals in a DSP Builder advanced blockset design use the built-in Simulink fixed-point types. Be careful if you compare your design with a floating-point reference.

Procedure

  1. Compare your implementation against a reference—a C/C++ bit accurate model, a MATLAB model, or a Simulink design.
  2. For a C/C++ model, save your output into a text file and write your C/C++ comparison script.
  3. For a MATLAB model, output the DSP Builder advanced blockset testbench data into a workspace or save it into data files.
  4. For a Simulink design, put the Simulink model in parallel with your synthesizable design.
  5. Use the Simulink scope to compare the two designs.
