Technical Overview

Validate and Debug Your Embedded C-PHY Data Links Quickly and Easily

The Keysight Technologies, Inc. MIPI C-PHY conformance test software for Infiniium oscilloscopes gives you a fast, easy way to validate and debug your embedded C-PHY data links. The C-PHY electrical test software allows you to automatically execute C-PHY conformance tests for your CSI2 and DSI2 architectures. The application automatically displays the results in a flexible report format. In addition to measurement data, the report provides margin analysis that shows how closely your product passed each test. The C-PHY conformance test software performs the complete range of tests to meet the physical layer requirement for your transmitter. It follows Section 9 of the MIPI Alliance Specification for C-PHY v1.0 and v1.1 and Section 1 of the C-PHY v1.0 and v1.1 Conformance Test Suite (CTS). The C-PHY conformance test software helps you execute the most difficult physical layers tests for transmitters (Tx test only) that can be measured with a high bandwidth oscilloscope.

Key Features

  • Complete MIPI Alliance Specification for C-PHYSM v1.0 and v1.1 Section 9 and C-PHYSM v1.0 and v1.1 CTS Section 1
  • Tests LP and HS tests for all speeds
  • Automated scope measurement setup, testing, and reporting for increased accuracy, time-savings, and repeatability
  • Automated margin analysis
  • API to enable advanced programming control of the application
  • InfiniiMax solder down probes provide high temperature testing from –55 to 150 °C

Save Time with the C-PHY Conformance Application

The C-PHY conformance test software saves your time by setting the stage for automatic execution of all the required electrical tests. The primary difficulty of performing electrical tests for C-PHY is connecting the oscilloscope to the target device, correctly configuring the oscilloscope measurement system for ultimate accuracy, issuing the proper commands to perform the tests, and then analyzing the measured results by comparing them to the limits published in the specification. The C-PHY conformance test software automates this work to provide rapid, accurate, and repeatable test execution.

Define Tests Easily

The C-PHY conformance test software extends the ease-of-use advantages of Keysight’s Infiniium oscilloscopes to testing C-PHY designs. The Keysight automated test engine walks you quickly through the steps required to define and configure the tests, execute the tests, and view the test results. Select all the tests, an entire category of tests, or specify individual tests. Save tests and configurations as project files and recall them later for quick re-testing or review of previous test. Straightforward menus let you perform tests with minimum effort.

Extensibility

You may add additional custom tests or steps to your application using the N5467B/N5467C User Defined Application (UDA) development tool (www.keysight.com/find/uda). Use UDA to develop functional “Add-Ins” that you can plug into your application.

Add-ins may be designed as:

  • Complete custom tests (with configuration variables and connection prompts)
  • Any custom steps such as pre or post processing scripts, external instrument control and your own device control

Automation

You can completely automate execution of your application’s tests and Add-Ins from a separate PC using the included N5452A Remote Interface feature (download free toolkit from www.keysight.com/find/scope-apps-sw). You can even create and execute automation scripts right inside the application using a convenient built-in client.

The commands required for each task may be created using a command wizard or from “remote hints” accessible throughout the user interface.

Using automation, you can accelerate complex testing scenarios and even automate manual tasks such as:

  • Opening projects, executing tests and saving results
  • Executing tests repeatedly while changing configurations
  • Sending commands to external instruments
  • Executing tests out of order
  • Combine the power of built-in automation and extensibility to transform your application into a complete test suite executive:
  • Interact with your device controller to place it into desired states or test modes before test execution
  • Configure additional instruments used in your test suite such as a pattern generator and probe switch matrix
  • Export data generated by your tests and post-process it using your favorite environment, such as MATLAB, Python, LabVIEW, C, C++, Visual Basic etc.
  • Sequence or repeat the tests and “Add-In” custom steps execution in any order for complete test coverage of the test plan
