Parallel_add Megafunction help

Hello everyone, I'm an absolute beginner with the software so I'd really appreciate if anyone could help me with a very simple issue.

 

I'm building a FIR filter using Quartus Prime Lite Edition and I want to place a parallel_add block to add all my bus streams, problem is I can't alter the block to have it look like, for example, the second image I uploaded called p_add_5 in order to be able to add five buses. How do I do it?

 

Thanks in advance to anyone who took the time reading

Double-click the block to open it's IP Parameter Editor. There you can set the number of input buses and their width.

Like so? Because even when I alter the size and width, there's no actual change in the look of the block. I figured maybe due to the fact that I'm using the Lite Edition?

Yes, but I think you have to refresh the block symbol you've already added. It's much easier to generate it as an IP from the IP Catalog and set the parameters that way.

Thanks Steven for your help on this. @Richardo, Steven is right. Generally it is recommended to instantiate the IP from the IP Catalog.
