QPHY-DDR2-OM-E Rev A
D2) Demo of Eye Diagram (Debug)
This configuration uses the saved waveforms found in the D:\Waveforms\DDR2 folder and run the Eye Diagram
test on the read bursts and the write bursts. All of the variables are set to their defaults except Use Stored
Waveforms is set to Yes and Use Stored Trace for Speed Grade is set to Yes. The limit set in use is DDR2-667.
The tests run are:

Eye Diagram – Write Bursts (Inputs)

Eye Diagram – Read Bursts (Outputs)
D3) Demo of All tests
This configuration uses the saved waveforms found in the D:\Waveforms\DDR2 folder and run all of the tests. All
of the variables are set to their defaults except Use Stored Waveforms is set to Yes and Use Stored Trace for
Speed Grade is set to Yes. The limit set in use is DDR2-667. All supported tests are run.
D4) Demo of All CKdiff-DQSdiff-DQse tests
This configuration uses the saved waveforms found in the D:\Waveforms\DDR2 folder and run all of the tests
requiring probing the clock and strobe signals differentially and the single ended data signal. All of the variables
are set to their defaults except Use Stored Waveforms is set to Yes and Use Stored Trace for Speed Grade is
set to Yes. The limit set in use is DDR2-667. All supported tests are run.
