1 Introduction

Overview

The MIPI® (Mobile Industry Processor Interface) C-PHY Frame Generator
software (also called as “Frame Generator” or “software”, in short) is a
stand-alone software utility. It provides semi-automatic control of the
C-PHY Signal Generator for physical layer tests, which is based on the
Keysight Technologies M8195A AWG (Arbitrary Waveform Generator).

The Frame Generator is a flexible tool for trouble-shooting and debugging.
It complements the full MIPI
provi des au tomated p hysic al layer c omp lianc e tests an d device
characterization. The Frame Generator generates the data sequences and
allows pattern changes as well as control of signal levels, data rate, and
timing parameters. The software runs on a standard Windows PC and
controls the hardware test resources through appropriate interfaces such
as LAN (Local Area Network).

2 Test Instrument Setup

Keysight recommends that prior to using the MIPI® C-PHY Frame
Generator software for connecting instruments, you must set up the test
instruments and establish the required connections.

• Connect the instruments to the controller PC by USB or LAN (AWG and
other instruments such as, signal and waveform generators).

• Establish all required cable connections between the instruments and
the DUT (device under test).

• Switch on the PC and instruments.

• Start Keysight “IO (Input Output) VISA (Virtual Instrument Software
Architecture) Connection Expert” and check the connections for the
instruments.

• Set the correct IP address for each instrument.

The software uses M8195A AWG modules for C-PHY output. For more
than one AWG module, the M8197A synchronizes the M8195A modules. It
supports up to three data lanes.

The AWG Setup can be used in two different modes:

• Four Channel mode

• Dual Channel mode

M8195A Four Channel Mode

Test Instrument Setup 2

This setup uses four channels on each AWG module to generate MIPI®
C-PHY signal. With this configuration, up to three data lanes can be
tested.

2 Test Instrument Setup

NOTE

M8195A Dual Channel Mode

This setup uses two channels on each AWG module to generate MIPI®
C-PHY signal. With this configuration, up to two data lanes can be tested.

Dual Channel mode is available only if you install the add-on license
‘C-PHY 2.0 Debug Tools 32G Sample Waveform Generation Add-on’.

3 Using the Software

NOTE

Connecting to the Instruments

Once you launch the MIPI® C-PHY Frame Generator, the software is in
“offline” mode. This indicates that user inputs have no effect until the
software has been connected to the instruments.

The CONNECTION section is displayed by default (see Figure 3). In this
section of the interface, you can enter all parameters that are necessary to
establish connections to the signal generator and the complementary
instruments, such as power supplies.

Figure 3 MIPI® C-PHY Frame Generator Connection Setup

Ensure that suitable cable connections between the PC and the
instruments are established, such as LAN or USB-to-GPIB connections.
The specific connection is reflected in the name-string of the
corresponding instrument. For details on naming conventions, refer to
the Keysight IO Libraries Suite Help.
