When I attempt to run "demo_ctrl.m" as described in (Xilinx XAPP948): "Hardware Acceleration of 3GPP Turbo Encoder/Decoder BER Measurement Using System Generator" Application Note, the figure windows open and then the system appears to go into an infinite loop.
The reason for this issue is that MATLAB R2006a operates differently to R14 sp3 regarding end of files.
The solution is to change the two ".m" files as described below:
In the file line 127 change from:
% while ~feof(fid)
In the "for" line 135 repeat above.
