QPHY-MIPI-DPHY VARIABLES
DUT bit rate in High-Speed mode in Mbps
This variable is used to set the oscilloscope timebase and sampling rate, see Clock Period Per Screen Division
for more explanation. The default value is 500 Mbps.
Note from the MIPI Specification
The actual maximum achievable bit rate in High-Speed mode is determined by the performance of transmitter,
receiver and interconnect implementations. Therefore, the maximum bit rate is not specified in this document.
However, this specification is primarily intended to define a solution for a bit rate range of 80 to 1000 Mbps per
Lane. Although PHY Configurations are not limited to this range, practical constraints make it the most suitable
range for the intended applications. It is anticipated a typical implementation will have a bit rate of approximately
500 Mbps per Lane.
Data P Signal Name
This variable is used to specify the Data Positive Signal. The default value is Dp.
Data N Signal Name
This variable is used to specify the Data Negative Signal. The default value is Dn.
Clock P Signal Name
This variable is used to specify the Clock Positive Signal. The default value is CLKp.
Clock N Signal Name
This variable is used to specify the Clock Negative Signal. The default value is CLKn.
DUT IC supply voltage
This variable is used to specify the IC supply voltage for the device under test. The default value is 1.2V
Save Acquired Waveforms
This variable is used to specify whether the user would like to save the acquired waveforms or not. The default
value is No. This setting is ignored if the Use Stored Waveforms variable is set to Yes. Waveforms will be saved
in the directory specified in the Waveform Path, Folder for HS Waveforms and Folder for LP Waveforms
variables.
Silent mode control
This variable is used to set QualiPHY to run in silent mode. In silent mode, no user interaction will be required.
The default for this variable is No.
Stop On Test to review results
This variable allows the user to pause the execution of QualiPHY after each test. The default for this variable is
No. When set to Yes, the script will stop after each test to allow for result reviewing. The setup will be saved so
that oscilloscope settings can be modified by the user. On resume, the setup will be recalled. Note that any new
acquisition done in the meantime might cause the script to misbehave.
