DSP Builder doesn't compile the Simulink files

Hello, thank you for see this post.
DSP Builder doesn't compile the Simulink files.

I'm using MATLAB R2013 Student Version.
I want to transform my original Simulink file
into VHDL file by SignalCompiler(DSP Builder)
in order to implement to CycloneⅢ EP3C 120 FPGA Development Board
by Quartus Ⅱ 12.1sp1 Web Edition(32bit).
But when I open the window of Signal Compiler
and push the button to compile the file, this message appears↓


Info: Generating HDL
Info: Analyzing Simulink model
Matlab Error
ﾃGﾃﾉﾁ[ alt_dspbuilder_mdl2xml (line 36)

Error: Error during compilation: Error: Error analyzing model see log for details.

This message also appears when I compile the existing test program.
For example,"in_out.mdl".


What is wrong???
