R/W Burst Generation

QPHY-DDR4 recommends to have a minimum of 10 R and 10 W bursts during each acquisition but for

greater statistical significance it is encouraged to have more. Programs which can communicate with the

DRAM and controller are widely available online. One example is Memtest86+ which is available for

download from memtest.org. When using Memtest it is recommended to use test mode 7, which will

randomly generate both R and W bursts. Additionally a custom program can be used to stimulate the

DUT.
