Sample Logic Analyzer Setup for LPDDR5 Decode
To create a configuration file
The Keysight-provided configuration files are valid only when used with the corresponding memory
probe and DRAM for which these are designed.
If you are using some other probing scheme or have a unique DRAM configuration that is not
addressed by these standard configuration files, then you must create your own configuration file
using the DDR Custom Configuration Creator tool. This tool simplifies the procedure of custom
configuration file creation and ensures that all the layout information (buses and signals definitions)
needed by LPDDR5 Decoder is included in the created configuration file.
This tool is included in the Keysight B4661A DDR/LPDDR Tools package and is available only after
you install this package.
To know more about this tool, refer to its online help that gets installed with this tool’s software.
To configure LPDDR5 Decoder Settings
To ensure that the acquired LPDDR5 data is decoded accurately, you need to configure the LPDDR5
Decoder settings. Use the Settings dialog to tell the decoder which chip selects will be used by your
device under test and to specify how the decoder should work.
To access the Settings dialog
From the main menu bar, select Tools > LPDDR5 Decoder > Settings .
or
In the Overview display, click the Settings button on the LPDDR5 Decoder tool.
NOTE
In the logic analyzer measurement setup, the LPDDR5 Decoder tool can be
attached to the U4164A Logic Analyzer module or a Data Import module as
displayed in the above screen. You can also attach a Filter tool to the
LPDDR5 Decoder tool to filter the decoded data display based on your
specific analysis requirements. But you cannot attach the LPDDR5 Decoder
tool to another decoder or Memory Analysis Viewer.
