USING QUALIPHY DDR2

QualiPHY DDR2 guides the user, step-by-step, through each of the source tests described in JEDEC Standard

No. 79-2E. 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 DDR2-667 (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) All tests that require 4 Probes

 D1) Demo of All Clock tests

 D2) Demo of Eye Diagram (Debug)

 D3) Demo of All tests

 D4) Demo of All Ck-diff-DQSdiff-DQse 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.
