The Display Serial Interface Specification defines protocols between a host processor and peripheral devices using a D-PHY physical interface. The DSI specification builds on existing specifications by adopting pixel formats and command set defined in MIPI Alliance specifications for Display Pixel Interface 2 (DPI-2) and Display Command Set (DCS).

Eurofins Digital Testing co-operates with Agilent Technologies on the DSI software automation for the Agilent Technologies U4421A and provides DSI protocol automation software for purchase. The tool is able to cover the DSI Transmitter Protocol CTS v1.04 and DSI Receiver Protocol CTS v1.02 as defined by

The Protocol conformance suite is a valuable tool to the Agilent Technologies U4421A offering automation for running DSI protocol conformance with the U4421A which requires minimal user input. The user interface allows easy configurationand saves all necessary logs in an HTML test report including the Raw captured test run data .ala file format in a pre-defined location. The User Interface gives a direct view of the passed/failed test cases and works for all configuration of DUTs up to four data lanes and one clock lane. The tool also allows configuration for a set of physical layer setting making your validation testing a non-miss in your development process.
