Option DDRA accelerates the analysis, validation, and conformance testing
of memory systems based on JEDEC Test Recommendations.
A single license of DDRA provides support for multiple generations of the
JEDEC DDR Standard; beginning with DDR1, DDR2, DDR3, while including
DDR derivatives LPDDR, LPDDR2, and GDDR5. Option DDRA supports
the common data rates in these standards alongside custom data rates up
to and beyond 2133 MT/s. Whether you are doing intensive signal integrity
analysis or debugging a specific memory transaction, DDRA will speed
your ability to trigger on and identify read and write bursts in the acquired

data record and then perform parametric measurements on the signals of
interest.
Auto-configuration Wizard Guides Easy Setup and Test Configuration
Analyze All Read/Write Bursts in the Entire Acquisition
Plot DQS and DQ Eye Diagrams for Reads and Writes
Perform JEDEC Conformance Tests with Pass/Fail Limits
Use Chip Select to Qualify Multi-rank Measurements
DDRA Wizard for Easy Test Selection and
Configuration
The wizard consolidates Tektronix experience and expertise in DDR testing
into a simple, easy-to-follow test selection interface. The user selects which
DDR technology, speed grade, and measurement group (reads, writes,
clocks, address, and control lines) they are testing, using check boxes to
select some or all measurements in a category. DDRA can then automate
oscilloscope scale selection, DQ and DQS level selections, and threshold
detection, then automate burst identification using search and mark. Search
and mark (for read/write measurements) data is used to identify and
separate all read vs. write bursts across the entire acquisition and qualify
measurement zones for use by DPOJET Advanced Jitter and Eye Analysis.
DPOJET will generate an eye diagram of the data and perform JEDEC
standard measurements qualified on read or write bursts. Measurement
configurations and JEDEC pass/fail limits are automatically applied for the
selected measurements. Every edge in each identified burst is measured,
then measurement results are included in statistics and plots for a complete
analysis of the acquired waveform.
