USING QUALIPHY LPDDR2

QualiPHY LPDDR2 guides the user, step-by-step, through each of the source tests described in JEDEC

Standard No. 209-2B. To do this, the user must setup a test session.

Users choose test configurations to run. There are several pre-loaded test configurations including:

• 1) Clock tests LPDDR2-667 (1 Probe)

• 2) CKdiff-DQse-DQSdiff 667 Write Burst (3 probes)

• 3) CKdiff-DQse-DQSdiff 667 Read Burst (3 probes)

• 4) Eye Diagram (3 Probes Debug)

• 5) Addr/Cmd tests (4 Probes)

• D3) Demo of All tests

The pre-loaded configurations provide quick and easy ways to begin compliance testing. You can create

your own custom configurations (see the Customizing QualiPHY topic for details).

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.
