Evaluation of the latency of each module on my design

Hi, 

In order to know how fast is my FPGA Stratix II 2SEP2S180F1020C3, I would like to evaluate the latency of my design on Alera Dsp Builder. I read that an approach is to obtain the latency of the arithmetic operators (multiplier, divider, parallel adder, gain) before evaluating the delay for each module. How can I do it? 

 

I also read about "Implementing Multipliers in FPGA Devices" on the site http://www.altera.com/literature/an/an306.pdf, but I'm still confused. 

 

So, I would also like to Know how I can use Dsp Builder to obtain the critical path or longest time between the input and the output of the data through the design. 

 

Thanks

You will need to synthesize your design with Quartus II and use timequest afterwords to analyze timing and detect the critical paths.
