Using Stratixv Precision DSP Blocks under m18x18_sumof2, set negate and loadconst to 0, and accumulator is an input . However get error "Invalid combination of preload and acc for instance". Does anyone see this, what is the reason for this. Thanks

Hi,

 

As I understand it, you seems to observe some issue with SV DSP block. Would you mind to share further details with me ie the Quartus version, IP used and some screenshots on the error observation so that I could perform issue replication on my side. Thank you very much.
