Efficient Verification & Debugging
for LPDDR5 Memory Interfaces
5G Is Coming – Can Your Testing Software Keep Up?
There’s a lot we don’t know regarding 5G. But we do know that it will be extremely fast and will take existing smartphones to the next level with higher resolutions, augmented/virtual reality and enhanced gaming experiences. LPDDR5 DRAM addresses the specifications of 5G by significantly increasing the data transfer and power efficiency compared to LPDDR4. Higher data transfer rates and faster signal speeds mean complex designs that push the boundaries of signal integrity and require higher performance measurements for compliance, debugging and validation.
The Tektronix LPDDR5 Transmitter Solution is an automated system-level test application that lets you quickly, efficiently and reliably validate and debug LPDDR5 designs to meet more than 50 electrical and timing measurements as defined in JEDEC.
Accelerate Your Time to Market
While DRAM validation is an essential step in product development to ensure the quality of a design, it is also very time-consuming and cumbersome. One way to limit this challenge is to reduce manual testing as much as possible. Our LPDDR5 Transmitter Solution allows you automate LPDDR5 signal integrity testing and cut your total test time in half. This reduces the overall feedback and testing cycle and allows companies to bring their products to market faster.
Debugging and Validation
Tektronix’s LPDDR5 Transmitter Solution puts control back where it should be—with the user. User-defined acquisition mode allows you to run LPDDR5 JEDEC compliance measurements by customizing scope settings like sample rate, record length, bandwidth and more.
Read/Write burst separation has always been a major issue for the memory validation engineer. Often, at a system level, there is no way to control the data traffic on the DDR bus. With new and improved burst separation algorithms, the LPDDR5 Transmitter solution not only allows simultaneous read/write burst detection but also improves test time and accuracy.
Validating s-parameters is often the primary concern when de-embedding LPDDR5 designs. With improved passivity checking, port assignments and plotting capabilities, not only does Serial Data Link Analysis (SDLA) enhance s-parameter file validation, it improves flexibility, saves time and increases confidence in the de-embedding process. Other debug software tools require you to complete the entire process to find results. Textronix’s LPDDR5 Transmitter Solution lets you detect problems at an earlier stage, allowing you to debug and optimize your designs more efficiently. SDLA features can also be helpful for DFE analysis.

P7700 TriMode Probes
One of the power saving features of LPDDR5 DRAM is an option to change the three differential signals CK, WCK, and RDQS into single-ended signals when running at data rates at or below 1600 Mbps. Depending on the use case, this single ended mode will also need to be thoroughly tested along with the default differential mode. P7700 series TriMode probes with new coaxial probe tip allows you to measure differential and single ended signals with one probe setup without de-soldering the probes. This simplifies the probing setup to test the LPDDR5 DRAM Single Ended Mode.
See our datasheet for a deeper dive into the TekExpress LPDDR5 Transmitter Solution software and how it can help you analyze and optimize complex LPDDR5 designs with ease.
SDLA Visualizer is a complete measurement circuit software that runs directly on an oscilloscope and provides extensive capability for computing embed and de-embed filters for real-time measurement and simulation. It controls the oscilloscope and creates live waveforms with these filters.
Newly introduced P7700 coaxial probe tips provide unmatched usability for connecting to today’s most challenging electronic designs. With the probe’s input buffer mounted only a few millimeters from the end of the tip, P7700 Series Trimode Probes provide exceptionally high signal fidelity to meet current and future challenges.
