Hi, I am trying to convert a Simulink model that contains several "Magnitude-Angle to Complex" blocks to HDL code. When running the Fixed Point Designer tool it fails at step 1.3 "Address unsupported blocks". However, "Magnitude-Angle to Complex" does support fixed point designs if the approximation method is set to "CORDIC", which I did. Are there any other settings that are needed? Or is there a bug in Fixed Point Designer? Thanks, Arne

Hi Arne, Thanks for bringing the issue to our attention. You are correct that the block "Magnitude-Angle to Complex" in CORDIC supports fixed-point. The issue is fixed in the new version of Fixed-Point Tool.
