System Generator. Estandard exception in FFT block

Question

I am trying to generate a bitstream file from a the FFTv4 block, but I get errors, one of the errors is about a file called 'fftv4_cw.ise' This is the error message I get:

standard exception: XNetlistEngine: An exception was raised: com.xilinx.sysgen.netlist.NetlistInternal: Could not copy 'C:/My Dropbox/Archivos sobre mi PFC/Files_Matlab/System Generator/Mis pruebas/bitstream/FFTv4/sysgen/fftv4_cw.ise' to 'C:\My Dropbox\Archivos sobre mi PFC\Files_Matlab\System Generator\Mis pruebas\bitstream\FFTv4/fftv4_cw.ise': No such file or directory at C:/Xilinx/dsptools/9.2.01.1028/sysgen/scripts/SgPass2Netlist.pm line 150

Does anyone have any idea of what to do? Does anyone could me give the file called 'fftv4_cw.ise?

By the way the link to my file is: https://www.dropbox.com/s/gpoeuefmbrpg5n9/FFTv4.mdl

Thank you for your help.

Answer 1

Just a guess but looking at:

'C:\My Dropbox\Archivos sobre mi PFC\Files_Matlab\System Generator\Mis pruebas\bitstream\FFTv4*/*fftv4_cw.ise'

Note that '\' used in the majority of this line is the proper windows directory separator. The '/' used in the rest of the error and the stared bit above is not the correct directory separator for windows.

For instance this:

'C:/My Dropbox/Archivos sobre mi PFC/Files_Matlab/System Generator/Mis pruebas/bitstream/FFTv4/sysgen/fftv4_cw.ise'

is using the forward slash which isn't the windows directory separator.

As such I would venture a guess that there is an error somewhere in your project that set the directories incorrectly which is resulting in this exception.

It is possible that whatever library is doing this would accept either forward or backward but I doubt it, and very much doubt it would allow both versions in one path.

EDIT: Got that backwards fixed...
