QPHY-DDR4 Test Configurations

Configurations include variable settings and limit sets as well, not just test selections. See the QPHY-
DDR4 Variables
section for a description of each variable value and its default value.

1) Clock tests DDR4-1600 (1 Probe)

This configuration will run all of the clock tests and requires 1 probe to be connected to the differential
clock. All of the variables are set to their default settings. The limit set in use is DDR4-1600.

2) Ckdiff-DQSdiff-DQse DDR4-1600 Write (3 Probes)

This configuration runs all the tests on write bursts in which 3 probes are required. A probe must be
connected to the differential clock, the differential strobe, and the single-ended data. All variables are set
to their defaults. The limit set in use is DDR4-1600.

3) Ckdiff-DQSdiff-DQse DDR4-1600 Read (3 Probes)

This configuration runs all the tests on read bursts in which 3 probes are required. A probe must be
connected to the differential clock, the differential strobe, and the single-ended data. All variables are set
to their defaults. The limit set in use is DDR4-1600.

4) Eye Diagram DDR4-1600 (3 Probes)

This configuration runs the Eye Diagram tests on both read bursts and write bursts. A probe must be
connected to the differential clock, the differential strobe, and the single-ended data. All variables are set
to their defaults. The limit set in use is DDR4-1600.

5) ADD/CTRL tests DDR4-1600 (4 Probes)

This configuration runs the Address/Control tests. A probe must be connected to the differential clock, the
differential strobe, the single-ended data, and the single-ended Address/Control signal. All variables are
set to their defaults. The limit set in use is DDR4-1600.

6) Pre/Postamble test DDR4-1600 (3 Probes)

This configuration runs all of the tests on the Preambles and Postambles for both read bursts and write
bursts. A probe must be connected to the differential clock, the differential strobe, and the single-ended
data. All variables are set to their defaults. The limit set in use is DDR4-1600.

D1) Demo of All Tests

This configuration uses the saved waveforms found in the D:\Waveforms\DDR4 folder to run all the tests.
All 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 DDR4-1600.
