Hi everybody!
I want to implement in vhdl a divider. So i want to use an ip core if i want to have a fast divider.
The divider can used for the calcul of interpolator. The algorithm for interpolator linear is : f= ya + lamda x ( yb -ya) and lamda= (x-xa)/(x-xb).
When i write a code vhdl ( vhdl structural) for adder, multiplier and substractor i compile it and i simulate it and evrything is ok.
So When i implement an ip core divider and simulate it i have at divider output
zero.
You can show in the attachement , the picture for the architecture, picture divider simulation and picture of the interpolation simulation.

I hope that i clarify my problem.
I will be grateful for your help.
Thank you.
Charko

PS: Sorry for my bad english.
