Why is the length set in the responder descriptor by Scalable Scatter-Gather DMA IP different compared to the actual transfer length of H2D Streaming transactions?

Description

Due to a problem in the Quartus® Prime Pro Edition Software version 24.3.1 and earlier, there might be transfer length mismatch between the length that is set in the responder descriptor by Scalable Scatter-Gather DMA IP and the actual transfer length of H2D Streaming transactions. This problem causes the value reported in responder descriptor to be different even though the actual number of bytes sent is correct.

Resolution

This problem will be fixed in a future release of the Quartus® Prime Pro Edition Software.
