Clarius Compliance DDR5 DRAM Receiver Test Solution

The DDR (Dual Data Rate) is a dominant and fast-growing memory technology. It offers high data transfer rates required for virtual computing applications, from consumer products to the most powerful servers. The high speed of these signals requires high-performance measurement tools. The Tektronix Clarius compliance DDR5 DRAM Receiver solution is an automated test application used to validate and debug the DDR5 designs of the DUT (Device Under Test) as per the JEDEC specifications. The solution enables you to achieve new levels of productivity, efficiency, and measurement reliability.

The Clarius compliance is a new-generation compliance test automation software platform that offers a range of features and benefits as follows:

• High asset utilization and faster test times - Disaggregated architecture to offload analysis from the oscilloscope.
• Easy workflow integration – Leverage REST API’s and SDK for faster automation.
• Unified user interface for all technology standards across Transmitter and Receiver.

Effortless test setup

Simplified measurement setup

• User-friendly configuration options streamline the setup process for all receiver measurements.
• Remote instrument control: Remotely control all test instruments including Anritsu’s MP1900A BERT, Astek’s fixtures for simplified operation.
• Automated DUT (Device Under Test) management: The Clarius DDR5 DRAM Rx compliance software automatically programs your DUT into the appropriate loopback mode for each test by saving your valuable time.

Customizable loopback scripts

• Pre-built script library: Leverage our library of pre-configured loopback scripts to quickly match common DUT configurations. Save time and effort by starting with a tested foundation.
• Effortless customization: Easily modify these pre-built scripts to perfectly align with your specific DUT requirements.
• Ultimate control: For highly specialized DUTs, take full control by loading and running your custom loopback scripts within the Clarius DDR5 DRAM Rx compliance framework.

Seamless calibrations

The Clarius DDR5 DRAM Rx compliance solution streamlines the calibration process, ensuring efficient and accurate testing. Automated calibration procedures guide you through the setup for both Astek's PTF fixture and replica channel cards.

Calibration results are conveniently stored within the software, readily accessible for current and future DDR5 receiver DUT testing.

DDR5 DRAM RX Tests

The Clarius DDR5 DRAM Rx solution streamlines the compliance testing process for DDR5 systems and devices, empowering user to achieve faster time-to-market with several innovative features.

Experience a user-friendly, step-by-step interface that accelerates test setup. Effortlessly configure key settings such as data rate, calibration, and test in a single intuitive global configuration window.

The interface groups tests logically by category like DQS Voltage sensitivity, DQ voltage sensitivity, DQS Jitter sensitivity and Stressed eye test and allows for individual test selection.

DUT (Device Under Test) Initialization: This option allows the user to enable/disable the Skip DUT Initialization. When enabled, it Pauses test execution for the user to manually initialize the DUT and continues with Loopback and tests.

Skip Loopback: This option allows the user to enable/disable the Skip Loopback. When enabled, it Pauses test execution for the user to manually put DUT into Loopback and continues with tests.

Pause Before Phase Change: This option allows the user to enable/disable the Pause Before Phase Change. When enabled, it Pauses test execution before running each phase.

Embed and De-embed filters

The Clarius DDR5 DRAM Rx compliance solution simplifies de-embedding filter management, allowing you to incorporate filter files (created by Tektronix's SDLA software) to account for PCB trace, package model, cable, and a portion of the PTF trace. This ensures the most accurate characterization of your DDR receivers, delivering reliable results for confident decision-making.
