Why do I see bandwidth decrement in multi-channels DMA testing with the Multi Channel DMA Intel® FPGA IP for PCI Express?

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 21.3 and earlier, the bandwidth figure reported by the software driver shipped with the Multi Channel DMA for PCI Express Intel® FPGA IP Design Example may decrement in multi-channels testing.

Resolution

This problem is fixed beginning with the Intel® Quartus® Prime Pro Edition Software version 22.4.
