All Dphy1 - X dialogs have controls for On, Category, Measure On, Measure, Burst Index, and Actions for Dphy1
buttons. When the HS Rise & Fall category is selected, DATA/CLK-VOD1, DATA/CLK-VOD0, and Find Levels
controls are also shown.

With HS (High Speed) selected as your Mode on the Mode and Input Selection Area of the MIPI D-PHY Dialog
(on page 135), Categories and Measurements on the Dphy1 - X dialogs vary in the following manner.

Note: For LP (Low Power) Tests, refer to the LP (Low Power) Tests (on page 136) topic.

Category and Measure Combinations for HS Dphy1 - X Dialogs

BRIEF HS CLOCK TO DATA TIMING TEST DESCRIPTIONS

With HS Clock To Data Timing selected in the Category field, the following Measure values are available:

FirstBit, TCLK-PRE, TCLK-POST, TSETUP, and THOLD.

Name

Purpose

FirstBit

To verify that the DUT HS Clock is properly aligned to the payload data signaling.

TCLK-PRE

To verify that the time that the HS clock is driven prior to an associated Data Lane beginning the
transition from LP to HS mode (TCLK-PRE), is greater than the minimum required value.

TCLK-POST

To verify that the DUT Clock Lane HS transmitter continues to transmit clock signaling for the
minimum required duration (TCLK-POST) after the last Data Lane switches to LP mode.

TSETUP

To verify the Setup time between the clock and data signaling is within conformance limits.

THOLD

To verify the Hold time between the clock and data signaling is within conformance limits.

BRIEF HS DATA TIMING TEST DESCRIPTIONS

With HS Data Timing selected in the Category field, the following Measure values are available:

TLP-01, THS-PREPARE, THS-ZERO, THS-PREPARE+ZERO, THS-SYNC, THS-TRAIL, TEOT, TREOT, and THS-
EXIT
