System Generator DAFIR block - non working "Decimate"

Hi all I have been designed block with filters in System Generator 10.1(+ MATLAB2007B). Problem now at DAFIR 9.0 component. For example "decimate by 2:1" parameter at this component. I see Output spectrum such as without decimate by 2. Same design in System Generator 9.2 (+MATLAB2007A) working OK. Whats happen? Best Regards Alex

Re: System Generator DAFIR block - non working "Decimate"

HI Alex,

I am not sure I totally understand the issue. Are you saying you are having a problem with the DAFIR v9.0 block decimating 2:1 in Sysgen 10.1, when it was previously working in 9.2?
Do any other models work in Sysgen 10.1 that previously worked in 9.2?

The best way to address this issue would be to submit a webcase at www.xilinx.com/support.

Re: System Generator DAFIR block - non working "Decimate"

Yes . Good projects  from System  Generator 9.2 with filters with DECIMATE option now not working in System Generator 10.1 .
To my opinion big army of  DSP engineers  must have same typical situation. 
Some times I see that I alone at Earth (with broken System Generator 10.1).

Re: System Generator DAFIR block - non working "Decimate"

Hi Alex,

There are a few things you can try that may resolve this:

1. Make sure you are updating any models generated with a previous version of Sysgen by using the xlupdatemodel command.
2. Re install the Xilinx tools. This includes ISE and Sysgen.
3. Check the Xilinx Answer Record database at www.xilinx.com/support.

If there are errors coming up make sure you note them and when they happen. If there are matlab errors present make note of those as well, there may be an issue with your matlab install. If you are able to create a webcase one of the DSP experts can look into it further. If you submit a case please include the model causing trouble and any observed errors.
