Why does the DMA write performance of the Intel® Stratix® 10 PCIe* Avalon®-MM Hard IP  implemented in Platform Designer degrade with Intel® Quartus® Prime Pro version 19.1?

Description

When using Intel® Quartus® Prime Pro version 19.1, the Intel® Stratix® 10 PCIe* Avalon®-MM Hard IP with DMA has a performance issue for DMA writes when using Platfrom Designer Avalon®-MM interconnect, which results in decreased throughput.

Resolution

Standalone implementations not using Platform Designer are not affected by this problem.
