QPHY-DDR4 Software Option
Using Qualiphy DDR4
QualiPHY DDR4 guides the user, step-by-step, through each of the tests in conformance with the
JEDEC DDR4 specification: JESD79-4. To do this, the user must set up a test session.
Before beginning testing, users choose the test configuration they wish to run. There are seven pre-
loaded test configurations. They are:
• 1) Clock tests DDR4-1600 (1 Probe)
• 2) Ckdiff-DQSdiff-DQse DDR4-1600 Write (3 Probes)
• 3) Ckdiff-DQSdiff-DQse DDR4-1600 Read (3 Probes)
• 4) Eye Diagram DDR4-1600 (3 Probes)
• 5) ADD/CTRL tests DDR4-1600 (4 Probes)
• 6) Pre/Postamble test DDR4-1600 (3 Probes)
• D1) Demo of All tests
These pre-loaded configurations provide quick and easy ways to begin DDR4 testing (see the QPHY-
DDR4 Test Configurations section for details on each configuration). The configurations are separated by
the signals which need to be probed in order to run each configuration. If the user does not want to run
any of these configurations, they can create their own custom configuration (see the Creating Custom
Configurations section for details).
The pre-loaded configurations are set up to run all of the tests required for compliance. If this is not what
the user wants, the variables can be modified (see the QPHY-DDR4 Variables section of this manual).
The variables are pre-loaded with the standard settings for compliance testing; however, the user may
choose to create their own configuration with the variables set as desired.
