issue in HDL coding tutorial on Matlab R2012a

Hi all,

I Just installed the HDL coder and was going through the tutorial (sfir filter function and relevant testbench). Float-to-Fixed Workflow ended smoothly but code generation ended with:

### Begin VHDL Code Generation ### Working on mlhdlc_sfir_FixPt as mlhdlc_sfir_FixPt.vhd ### Generating Resource Utilization Report resource_report.html Error occurred when running post codegeneration tasks Error: failed to run post code generation tasks: MATLAB:save:invalidVarName 'Documents\MATLAB\filter_sfir\codegen\mlhdlc_sfir\hdlsrc\codegen_info.mat' is not a valid variable name.

Any idea?

Thanks

'Documents\MATLAB\filter_sfir\codegen\mlhdlc_sfir\hdlsrc\codegen_info.mat' is a partial path. This path probably won't work unless the curfrent working direcctory of MATLAB is the one containing the referenced 'Documents' subdirectory. is that the case?

What are you specifying for your code generation directory, if any? Can you specify an absolute path?

The entire path was:

D:\data\S2100013\My Documents\MATLAB\filter_sfir\codegen\mlhdlc_sfir\hdlsrc\

I copied the directory containing the exercise into: D:\data\S2100013\matlab_prova\filter_sfir\codegen\mlhdlc_sfir\hdlsrc\

After this I could pass this step. It looks like the empty character in "My Documents" was causing the issue:

Thanks Alberto

This is a known issue in R2012a and has been in subsequent releases.
