HDL Code Generation "unhandled type"

I am trying to work through some of the tutorials on HDL Coder. However, I get the following error when trying to generate the code for the Symmetric FIR Filter

unhandled type
Use help codegen for more information on using this command.

Error in Manager>wfa_generateCode at 535

What exactly is the error here and how do I fix it?

I am running MATLAB R2014b on Ubuntu 14.04.

Thanks In Advance

Alex

you might have tried to generate code from the whole model. can you try this?

 makehdl('sfir_fixed/symmetric_fir')

[Alex Biddulph]

I have been following the instructions listed in the link I specified.

Here is the result of running that comand

>> makehdl('sfir_fixed/symmetric_fir')
Error using getmodelnodename (line 40)
Could not find subsystem 'sfir_fixed/symmetric_fir' in the model 'simulink'

Error in hdlcoderargs>isvalidstartnodename (line 117)

Error in hdlcoderargs (line 55)

Error in privmakehdl (line 10)

Error in makehdl (line 75)
privmakehdl(varargin{:})

[Tim McBrayer]

This is the error message you get when you haven't opened the model sfir_fixed. HDL Coder needs the model open and in memory before it can generate HDL code.

Here is a screenshot of my MATLAB window. You can see the project is open in the HDL Code Generation tab on the right-hand side.

Is 'sfir_fixed/symmetric_fir' the right system/sub-system for my setup?

Hello There, I have the same problem as Alex explained it . did you solve this problem ?

[Ganesh Gaonkar]

Hi Tamer, Are you trying to generate HDL code for 'sfir_fixed' Simulink model or trying MATLAB to HDL convertion workflow mentioned here ? Which error among the 2 above mentioned errors you are receiving at your end?

[Shrivathsav Seshan]

Ganesh, I am receiving the error that Alex received in his original post. I am trying the example workflow for MATLAB code to HDL from the link you posted. What is your advice

[Kiran Kintali]

the demo should work out of the box unless there are some install issues.

this is not an expected error. please contact technical support with reproduction steps.
