Hi all, A question related to this:
Like Glenn, we never had Fixed point toolboxes (Fixed point Toolbox and Simulink Fixed point) installed, and still were able to compile our correlator designs using 11.5 and Matlab2009b. I recently upgraded to ISE 14.5 with Matlab 2012b as well as upgraded libraries to the latest version of casper-astro/mlib_devel. Even in the current installation, we do not have Fixed point toolboxes (names have changed to Fixed-point designer Toolbox, Simulink Fixed-point as Jonathan has mentioned). The current fft_wideband_real block has some differences compared to the older version that I was using so far and it seems it now requires Fixed-point Toolbox. I am getting errors that this particular toolbox has not been installed. I am not sure if there are other blocks that give similar errors. Does anyone have any experience with this and provide some insight as to how to deal with this situation? Specifically, (1) Is there any way to use the latest fft_wideband_real block without Fixed-point Toolboxes? (Glenn, have you tried this?) (2) Does one have to install both the Fixed-point toolboxes (Fixed-point designer Toolbox, Simulink Fixed-point) or just the Fixed-point designer Toolbox? (I have attached lists of toolboxes in our previous and current installation.)
