Teledyne LeCroy QPHY-DDR4 - Manual (Page 20)

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.
