QPHY-DDR4 Software Option
Appendix A: File name conventions for saved waveforms
QPHY-DDR4 saves the waveforms from each acquisition using a specific file name convention. This
specific waveform name definition allows the user to re-run any acquisition to recreate specific test
results. When running QPHY-DDR4 in demo mode the variables need to be setup up appropriately to let
QPHY know which waveform should be recalled.
Here is a typical QPHY-DDR4 waveform name: C2_CKDQ0DQS3_DQS3_DQS3_00014.trc
• C2: This is the channel used to acquire the signal. In this case C2 was used. When running in Demo
mode this portion of the waveform must match the Channel Index variable.
 Possible values: C1, C2, C3, C4
• CKDQ0DQS3: This is the probe setup used during the acquisition. When running in Demo mode this
portion of the waveform must match the Probe Setup for the test being run.
 Possible Values: CK (CK diff probe Setup), CKDQxDQSx (CK-DQ-DQS 3 probe setup),
CKDQxDQSxAx (CK-DQ-DQS-Add 4 probe setup), etc.
• DQS3: This is the signal name for this trace as it was set using the Signal Name variable. When
running in Demo mode this portion of the waveform must match the Signal Name variable.
 Possible values: DQ0-63, DQS0-15, etc.
• 00014: This is the file index. QPHY will automatically increment this by one on each run. When
running in Demo mode this portion of the waveform must match the Recalled Waveform File
Index variable.
 Possible values: Any five digit number
