Validate and Debug Your Embedded D-PHY Data Links Quickly and Easily
Keysight Technologies, Inc. MIPI® D-PHYSM conformance test software for Infiniium
oscilloscopes gives you a fast, easy way to validate and debug your embedded D-PHY data
links. The D-PHY electrical test software allows you to automatically execute D-PHY electrical
checklist tests for CSI-2 and DSI architectures, and displays the results in a flexible report
format. In addition to the measurement data, the report provides margin analysis that shows
how closely your product passed or failed each test.
The D-PHY conformance test software performs a wide range of tests required to meet the
physical layer requirements per Section 9 of the MIPI Alliance Specification for D-PHY v1.2
and Section 1 of the D-PHY Conformance Test Suite (CTS) v1.2. The D-PHY conformance test
software helps you execute the most difficult physical layer tests for transmitters (TX tests
only) that can be measured with a 4-GHz or higher-bandwidth real-time oscilloscope. Although
there are not currently any requirements for physical layer compliance verification, it is highly
recommended that every MIPI D-PHY link be tested against the limits of the physical layer
specification to ensure that it is compliant to the specification and to minimize concerns with
protocol level interoperability.
Features
The D-PHY conformance test software offers several features to simplify design validation:
– Complete MIPI Alliance Specification for D-PHY v1.2, section 9 and D-PHY CTS v1.2,
section 1
– User selection of tests and configuration of data rate
– Automated scope measurement setup and programming for increased accuracy,
time-savings and repeatability
– Advanced debug modes for troubleshooting
– Automated margin analysis and pass/fail conformance reporting
With the D-PHY conformance test software, you can use the same oscilloscope you use for
everyday debugging to perform automated testing and margin analysis based on the MIPI
Alliance Specification for D-PHY v1.2, section 9 requirements and D-PHY CTS v1.2, section 1.
