Adding Array in FPGA

[guilio_2008]

I noticed there isn't a add array elements in FPGA and was wondering how I can go about doing this task another way?  Looking for something wiht less overhead as well.  Any takers?  I tried using a for loop, index array, then run that index into an addition element, from the additioin element to a shift register, then the shift register into the other end of the add element.  This works for the first N (for loop interation), but after that, it just keeps climbing in values.  Any ideas?

You cannot build a variable-sized array in LV FPGA; all arrays must be fixed sized.  See the help.

Another option would be to use a memory or FIFO block which is configured with the expected maximum number of elements.

Depending on your use case you may use the one or the other
