IP Altera FIR filter 6.1 multiple coef set problem

[Altera_Forum]

Hi! 

 I created a FIR filter using Altera FIR IP v.6.1 (and Quartus v6.1).   The characteristics of my filter are:    -Rate specification : Decimation : 8 -Number Of Input Channels : 1 -Input Number System : Signed Binary  -Input Bit Width : 12 -Output Specification : Based On Method : Bit Width Only Full Resolution   -I enter two different coefficient sets with 32 coefficients each   -Coefficients Scaling Auto Bit Width 8 -Device Family : Stratix II -Structure : Distributed Arithmetic : Fully Parallel Filter -Pipeline Level : 1 -Data Storage : Logic Cells -Coefficients Storage : Logic Cells   The problem is : the filter takes only the first coefficients set whatever the signal ("1" or "0") at the input "coef_set" of the filter.   I tried to create the same filter in Single Rate and it works well.   Why the coef_set selector does not work with Decimation?

I would stay away froim the version 6.1 version fo the FIR compiler. 

I cannot say for sure, but I think that I recall reading about lots of issues with this compiler (in that version).  Upgrade to the latest tools (or at least 7.2) and see if the issue goes away.
