Why does simulation of the Intel® Arria® 10 or Intel® Cyclone® 10 GX Avalon® Memory-Mapped (Avalon-MM) DMA Interface for PCI Express* example design testbench not include a DMA process?

Description

Due to a problem with the Intel® Arria® 10 or Intel® Cyclone® 10 GX Avalon® Memory-Mapped (Avalon-MM) DMA Interface for PCI Express* example design testbench DMA transactions are not processed.

Resolution

In current versions of the Intel® Quartus® Prime Design Software, to correctly simulate DMA processes, modify the 'apps_type_hwtcl' parameter from '3' to '6' within the 'altpcie_a10_tbed_hwtcl' module instantiation in the file 'dut_pcie_tb_ip.v'.

This problem is fixed starting with the Intel® Quartus® Prime Pro Edition Software version 21.4.
