Dsp Builder - create NCO or ReesSolomon vhdl and matlab files bit exact

Hello,

When I am creating a block of NCO or Reed Solomon in DspBuilder => MegaCore Function in simulink and I want to get Matlab files and VHDL files will be bit exact

For RS I did not get any Matlab files.

For both of them when I run simulation in model-sim I get a missing file errors and that despite i compile everything I could and I ran the tcl that created in folder.

what i need to do for get all files in vhdl and matlab files bit exact ?

i use in matlab R2015a

and altera Dsp Builder 15.0.0.145 web edition.

Thx.
