How FIR 5.0 can dont use DSP Mult?

hi all,

 

I want to implement a correlation function. then, I use a FIR Core v5.0 which its coefficents is reloadable. it is ok and works.

but, Data and correlation width is only 2 bit, and I dont want to use DSP Mults, but the core dont understand it!
also, I use attributes and change synthesis option, for no using DSP48 slices, but it still use it.

by the way, I wanted to use DA FIR5.0, but DA FIR5.0 cant apply online coefficent reload. 

Now, I dont know, what can I do. Can anyone help me?

 

thanks in advance,

Ehsan
