As I knew it was altaccumulate IP at Cycloneiii, but this IP is obsolete at Cyclone V.
How can I implement an accumulator in Cyclone V?
What is a relevant IP for this issue ?
We should still have the accumulator. You can refer to https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/cyclone-v/cv_5v2.pdf page 3-4
Thank you for your answer.
I've built a simple accumulator and it seems OK.
You can close the case.
