The DDR (Dual Data Rate) is a dominant and fast-growing memory technology. It offers high data transfer rates required for virtually computing applications, from consumer products to the most powerful servers. The high speed of these signals requires high-performance measurement tools. The Tektronix TekExpress DDR Tx is an automated test application used to validate and debug the LPDDR5-5X designs of the DUT as per the JEDEC specifications. The solution enables you to achieve new levels of productivity, efficiency, and measurement reliability.

LPDDR5-5X system level tests
The Tektronix TekExpress DDR Tx solution reduces the effort and accelerates the compliance testing for DDR systems and devices with several unique and innovative capabilities.
The TekExpress DDR Tx application provides a simple, step-by-step, and easy-to-use interface to speed up the testing process. User can select the memory technology of interest in Device, Data Rate, Burst Detection Method, select the probing configuration used for Clock, and strobe in the Setup DUT panel. Perform the test selection in the next step as per the measurement group (Clock, Command Address, Data Strobe, and Data for both Read and Write traffic (or bursts)) and individual measurements within the group provide different methods of Burst detection.

Acquisitions
The TekExpress DDR Tx application comes with a unique feature to select or deselect the signal. Once the signal is selected in the acquisition panel, the user can select the signal source connected to the oscilloscope.

De-embed filters
Easily de-embed the interposer and the probe effects by applying suitable de-embed filters within the LPDDR5-5X standard.
Comprehensive measurements
The option LPDDR5SYS adds a long list of JEDEC specific measurements for LPDDR5-5X memory standards. The TekExpress DDR Tx application covers Electrical measurements, Timing measurements, and Eye Diagram measurements as per the JEDEC standards.
Automated Read and Write Burst detection
The TekExpress DDR Tx provides different ways to detect the burst cycles that are used to perform measurements:
- Read Write Bursts – when the DUT traffic is configured to send both Read and Write bursts then this method is used for burst detection.
- Write Only – when the DUT traffic is configured to send all Write Bursts then this method is used for burst detection.
- Read Only – when the DUT traffic is configured to send all Read Bursts then this method is used for burst detection.
- Visual Search – defining Visual Trigger areas to identify and gate area of interest for measurements
Test selection
The TekExpress DDR Tx test selection panel allows the user to select the various measurements supported by the application.
- Supports 158 measurements of LPDDR5-5X System Transmitter Tests as per LPDDR5 JEDEC specification:
- 33 Clock measurements.
- 11 Write Clock measurements.
- 58 Write Data measurements.
- 1 Write Data tDQ2DQ measurement.
- 30 Read Data measurements.
- 13 CA Rx Specification measurements.

Results and reporting with waveform
The measurement configurations and JEDEC pass/fail limits are automatically applied for the selected measurements based on the memory specification and the selected speed grade. The results report includes DDR measurements of statistical data, measurement plots, and the screenshot of the waveforms with the cursors. Hyperlinks within the report allow you to navigate between the sections.
When test execution is complete, the application automatically opens the Results panel and displays the summary of test results.
Verification versus debug
The TekExpress DDR Tx application provides a comprehensive set of JEDEC timing and electrical measurements for the LPDDR5-5X standard. Also, it provides access to the DPOJET Advanced Jitter and Timing analysis engine that allows flexibility to reconfigure the existing measurements or to perform new measurements that are not defined by the JEDEC specification using new user-specified test limits.
Oscilloscope triggering and waveform identification
The Tektronix Pinpoint® trigger system provides the most comprehensive high-performance trigger system in the industry. The Pinpoint trigger system encompasses threshold and timing related triggers, Dual A and B Event Triggering, Logic Qualification, Window Triggering, and Reset Triggering.
The Advanced Search and Mark feature in the Tektronix MSO/ DPO5000, DPO7000, and MSO/DPO70000 Series oscilloscopes find unique events in the waveforms. It scans acquired waveform data for multiple occurrences of an event and marks each occurrence.
The Search and Mark feature has a close relationship with the Pinpoint trigger system since they both can be used to discriminate signal characteristics. Search and Mark includes signal-shape discrimination features of the Pinpoint trigger system and extends them across live channels, stored data, and math waveforms.
The Visual Trigger makes the identification of the desired waveform events quick and easy by scanning all the acquired analog waveforms and comparing them with the geometric shapes on the display. By discarding the acquired waveforms which do not meet the graphical definition, Visual Triggering extends the oscilloscope’s trigger capabilities beyond the traditional hardware trigger system.
