May 22, 2014 - While Agilent W4633A BGA interposer is used with Agilent E5849A probes for high-data-rate DDR4 x4 or x8 DRAM designs, Agilent W3636A BGA interposerálets engineers probe DDR3 x16 nonstacked DRAM more than 2 G deep. Both interposer solutions, whichácapture address, command, and data signals for debugging designs and making validation measurements, are designed for use with Agilent U4154A logic analyzer system and support data rates testing beyond 2,400 Mbps.

Second Interposer Solution Offers Probing for DDR3 x16 DRAM Designs

SANTA CLARA, Calif. – Agilent Technologies Inc. (NYSE: A) today introduced two new interposer solutions for testing DDR4 and DDR3 DRAM designs with a logic analyzer. Both interposer solutions provide fast, accurate capture of address, command and data signals for debugging designs and making validation measurements.

The Agilent W4633A BGA interposer is used with Agilent E5849A probes for high-data-rate DDR4 x4 or x8 DRAM designs. The Agilent W3636A BGA interposer allows engineers to probe DDR3 x16 nonstacked DRAM more than 2 G deep.

As the industry transitions to DDR4 data rates up to 3.2 Gb/s, engineers working on next-generation memory systems - such as those used in servers and embedded devices - face significant challenges. Probing and accurate signal capture are becoming increasingly critical for debug and validation of new designs.

Both interposer solutions provide direct access to the balls of the DDR4 x4 or x8 DRAM with low loading and minimal impact to signal integrity on embedded system design. The probe works in existing designs and eliminates the need for up-front planning or redesign. Both interposer solutions are designed to be used with the Agilent U4154A logic analyzer system, the world's fastest logic analyzer with 4-Gb/s state speed and 2.5-GHz trigger sequence speed.

"Our customers need more accurate tools to both achieve the data rates required for next-generation memory systems and implement power-saving functionality," said Jay Alexander, vice president and general manager of Agilent's Oscilloscope and Protocol Division and chief technology officer, Keysight Technologies. "With the new DDR4 BGA interposer, E5849A probe and U4154A logic analyzer system, engineers are ready to test DDR4 data rates beyond today's data rates of 2400 Mb/s."

The W3630A Series DDR3 BGA probes are used with oscilloscopes and logic analyzers to perform physical-layer and functional tests for data rates up to 2400 Mb/s with the U4154A logic analysis system.

Features of the Agilent DDR3/4 test solutions include:

The B4622B DDR2/3/4 and LPDDR/2/3 protocol compliance and analysis toolset, which provides four different software tools: two for functional protocol compliance checks, one automated physical address trigger setup tool, and one tool that provides an overview of system performance through bus statistic information and a histogram view of address access. These tools help reduce memory designers' troubleshooting time and increase productivity and efficiency in DDR design validation work.

The B4621B DDR2/3/4 protocol decoder software, which translates acquired signals into easily understood bus transactions showing associated data bursts. Valid read and write commands are decoded to include row and column addresses and the complete data burst associated with the command. The B4621B bus decode software anticipates key system attribute inputs from default DDR2, DDR3 or DDR4 probing configurations or the DDR setup assistant tool to accelerate decode of DDR2, DDR3 or DDR4 bus signals.

The DDR eye scan/eye finder, which provides unique eye-scan capability to automatically place the sampling point in both time and voltage within the eye on each individual channel for optimal sampling reliability. The DDR eye-scan display provides bus-level signal integrity insight for a qualitative comparison of all signals scanned under the same conditions.

The DDR setup assistant tool, which guides users through a short series of questions and pull-down menus to assist in tuning state mode measurements on DDR2/3/4/ or LPDDR2/3/4 measurements.

The DDR configurator creator tool, a new tool added to the Agilent DDR setup assistant and eye-finder software package. The tool allows engineers to define the footprint's layout according to a custom probing solution used in the DDR/LPDDR setup and then create an XML configuration file based on the footprint information.

The U4154A logic analysis module with 4-Gb/s state speed and 2.5-GHz trigger sequence speed enables full capability so engineers can reliably trigger and capture DDR4 signals at 3.2 Gb/s. When used with the new DDR4 probing solution, the B4621B decoder and B4622B compliance software toolset, this module provides full test capability for system integration in the memory industry.
