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.
