QPHY-DDR3 TEST CONFIGURATIONS

Configurations include variable settings and limit sets as well, not just test selections. See the section for
a description of each variable value and its default value. See the QPHY-DDR3 Limit Sets section for
more information about the limit sets.

1) Clock tests DDR3-1333 (1 Probe)

This configuration runs all of the clock tests. All of the variables are set to their defaults. The limit set in
use is DDR3-1333. The tests run are:

• tCK(avg)
• tCK(abs)
• tCH(avg)
• tCL(avg)
• tCH(abs)
• tCL(abs)
• tJIT(duty)
• tJIT(per)
• tJIT(CC)
• tERR(n per)

2) CKdiff-DQse-DQSdiff 1333 Write Burst (3 Probes)

This configuration runs all of the tests that are run on write bursts of the DDR3 signals in which 3 probes
are required. All of the variables are set to their defaults. The limit set in use is DDR3-1333. The tests run
are:

• Eye Diagram – Write Bursts (Inputs)
• SlewR
• SlewF
• VIH(ac)
