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, 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, Dale On Thu,

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

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). Dave On Sep 26, 2013, at 8:32 AM, Nimish Sane wrote: Thanks Jack! I was thinking of using

Hi, Wes, You could probably coax the current 10 GbE block to do multicast. Since the 10 GbE block assumes that all locally connected devices (i.e. on the same subnet) have the same the first 24 bits of the IP address as the core's own IP address. So you could choose a block of 256

Yes, that is what I am trying right now (old netlist). Jack's FP license had reached its limit. So that did work anyways. Thanks, Nimish On Thu, Sep 26, 2013 at 1:58 PM, David MacMahon dav...@astro.berkeley.eduwrote: Hi, Nimish, If you have a netlist you are happy with then just use that

What about just checking out an older version of the libraries pre-'fi'? On Sep 26, 2013 2:32 PM, Nimish Sane nimishs...@gmail.com wrote: Yes, that is what I am trying right now (old netlist). Jack's FP license had reached its limit. So that did work anyways. Thanks, Nimish On Thu, Sep

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
