Reloadable coefficient doesn't work. FIR compiler 5.0

Hello!

I'm using  FIR compiler 5.0 on Spartan-6 board.

I try to build filter with changeable bandpass range, and use reloadable coefficients for this. But when I initialize coefficient reloading, it doesn't give effect. When I start Initialization of coefficient loading, signal coef_ld is pulsed, when falling edge  coef_ld signal coef_we becomes = '1' and doesn't change while coefficients are loaded from external storage. It's looks great, when i modeling in iSim (attached image), but in real life it doesn't work. What can be the reason that the filter does not change coefficients?

Any help to fix this problem is highly appreciated.

 

Thanks!

Alex
