Can I use fixed-point tool with dsp builder?

I have created a design with dsp builder Advanced Blockset and now I want to optimize the word length with the fixed-point tool in simulink. But I find that the fixed-point tool can't log the simmax and sinmin values. I have compared the fixed-point tools' configuration with the simulink's demo, and can't find difference. I'm not sure whether dsp builder support fixed-point tool. Please give some information about this . Thanks.

    The Simulink HDL Coder tool from MathWorks works with the Fixed-Point Advisor, and can be used with Quartus II. More info at mathworks-dot-com/products/slhdlcoder.

    Hi , ecigan

    I know that Fixed-Point Advisor can build enviroment for searching optimal floating-to-fixed conversion. But I have not found how to relate Fixed-point advisor and Quartus. Can you give a example? Thanks.
