Thanks a lot Andrew!
We are using pfb_fir_real. So that is not a problem. I will try the new FFT
block very soon.
Thanks,

Hi Dale
Just pushed my update to ska-sa repo on github. Replacement script
(doubles2unsigned.m) seems to be working (for basic simulations,
currently running more in-depth tests).
Calls to fi() have been removed from the FFT family as far as I can
tell, there are some still lurking in the ne
What about just checking out an older version of the libraries pre-'fi'?

Yes, that is what I am trying right now (old netlist). Jack's FP license
had reached its limit. So that did work anyways.

Hi, Nimish,
If you have a netlist you are happy with then just use that one. There is no
need to regenerate a new netlist unless you want a bugfix or a change in
latencies (e.g. to improve timing).

Thanks Jack! I was thinking of using the black box which was generated
using earlier toolflow and library, but this may be better. If someone with
a license is willing to do this, please let me know. I will be happy to
share the mask parameter configuration.
The most annoying part of this is that
If you're really desperate, presumably someone on this list with a license
can precompile the fft block for you, which you could then black box? Or
generate the block, disable the init script, and send it to you?
Not necessarily suggesting that this is a better strategy than just
reverting your li
Hi Andrew,
We are desperate to complete a design by this week in order to support our
software development team over the weekend, but we are stuck right now due
to this issue. If you do manage to find a work-around and can provide a
block update, please let us know.
Many Thanks,

Hi Dave
I use fi to convert coefficients to be stored from parallel matlab
double precision format into single unsigned words that will accurately
be converted back by slicing and using convert blocks. I think it is
possible to create the same functionality, I will have a quick try.
Cheers

Hi, Andrew,
Can you elaborate on how you use fi? I think much of the functionality can be
accomplished by judicious use of the multiplication, rounding, and modulo math
(for wrapping) or "x(x>max)=max" (for saturation). It might be possible to
create a "clean room" replacement function that d
Hi
Thanks Andrew! Would you know approximately how much time it would
take for you to look into this? Meanwhile, would you know the latest

Replacing fi will be difficult. I will probably rather provide a
parameter
Hello all,
This is really great. I'm currently working on upgrading as well and am
waiting to hear back from mathworks for a quote for the Fixed Point Designer
(the FP toolbox + FP simulink). The reason I'm upgrading is to be able to use
the new PFB modules because they use significantly

have Fixed

Hi
I do use the fi constructor to generate fixed point values when
generating twiddle values for storage.
I will see if it can be done in another way as it seems wasteful to
require a license just for that.

Thanks, Nimish,

Thanks, Nimish,
Looking at the recently updated casper-astro repository, the following mask
init scripts use the "fi" function (technically a "constructor", I think) to
crete fixed point objects:
casper_library/cosin_init.m
casper_library/feedback_osc_init.m
casper_library/pfb_fir_coeff_gen_ini
Some more investigation:
I am seeing these messages:
License checkout failed.

Thanks. I was hoping to narrow it down a little more than that. There's a lot

To be precise, that is the only green block in the design apart from bunch

The design only has fft_wideband_real block, and whenever I click
"Apply/Ok" or "Update Diagram", I get these error messages. These are the
only error messages I see in Matlab window. So it is definitely the
fft_wideband_real block.

Thanks, Nimish,
Is there any other info that might help pinpoint which block and/or init script
is causing Matlab to look for a Fixed_Point_Tollbox license?

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
lib
As one data point I'm successfully compiling designs w/o the fixed point
toolboxes. I haven't tried simulating a large design which is where it's
claimed to be needed with busses wider than 53 bits or whatever it is

Hi fellow CASPERians,
This is a question that comes up periodically. At SAO we are now paying full
fare for Matlab licenses so the cost impact of an imperfect understanding can
be significant.
