details on PARALLEL_ADD megafunction

Hello every one,

I just want to know if someone knows what is the specific implementation of the PARALLEL_ADD megafunction.

I want to implement a reduction tree to calculate the sum of 32 entries of 16 bits each using 4:2 carry save adders but I don't know if this megafunction already implements the parallel adder by using some form of p:q carry save adders in which case it will save me the task of implementing my design and checking if the maximum frequency met the restrictions (200 MHz).

Thanks in advance!!

    Whether it does that or not, you will still have to build it to check the max frequency.

    Why dont you build the parrallel_add megafunction and check the floorplanner to see if it did what you wanted!
