Setting Up for LPDDR Bus Decode 2
Logic Analyzer Measurement Setup for LPDDR5 Bus Decode
To configure the Logic Analyzer measurement setup for LPDDR5 decode, you use the DDR Setup
Assistant. This tool is available at no charge as part of the Keysight B4661A memory analysis
software package.
The DDR Setup Assistant is a wizard-like application that helps you set up your logic analyzer
properly for LPDDR data capture and analysis. This tool simplifies the measurement setup by guiding
you through the setup process and automating the threshold voltages and sample positions settings
for control/address signals.
The following two scenarios are applicable when using the DDR Setup Assistant to create Logic
Analyzer measurement setup.
Scenario 1: You are using a standard probing solution
In this case, a standard LPDDR5 configuration file is available for the probing solution being used. A set of standard
LPDDR5 configuration files is provided when you install the LPDDR5 Decoder software.
The DDR Setup Assistant wizard automatically:
• loads the appropriate standard configuration file matching the standard probing solution details that you provided in
the wizard.
• sets the required buses and signals.
• adds the LPDDR5 Decoder tool and a Listing window in the Logic and Protocol Analyzer GUI.
Scenario 2: You are using a custom probing solution
In this case:
1. Create your own custom LPDDR5 configuration file. You use the DDR Custom Configuration Creator tool installed with
the B4661A Memory Analysis SW package to create custom files.
2. Run the DDR Setup Assistant and load your custom configuration file in the third step of the wizard as shown below.
