Variable Precision DSP in Arria V Devices

hey folks, I am new to altera stuff. I am porting my design from xilinx devices to altera devices. In that process am facing problems with DSPs porting. I am not finding dsp in altera similar...

Hey Tricky,

You are right, now days every device has many luts. it's not a problem to use luts for adder.But module which m porting is instantiated some 70 times, in that if i take 50 luts for this module(adder logic outside) it will results in 3500 luts approximately.which is a huge number. so to avoid this, m trying to infer dsp so that my design will be optimized.

I am targeting arria v devicce.

I implemented same way in verilog and synthesized in Quartus II 14.0 (trial version). But it's inferring adder with extra logic only.

Thanks.
