LeCroy Corporation, the worldwide
leader in protocol test solutions, has announced a new cost effective validation
platform that provides DDR4 bus and JEDEC timing analysis. Based on LeCroy's
first generation DDR3 analyzer, the new Kibra 480 platform features proprietary
probing technology designed to non-intrusively monitor DDR4's higher transfer
speeds without time consuming signal calibration and setup. The system analyzes
bus traffic while identifying timing violations and displays both commands and
errors using a full function waveform viewer. With support for testing both
DDR3 and DDR4, the system allows designers to speed memory integration and
ensure design manufacturability.
DDR4 is the next evolution of the
double data rate memory technology currently under development by the JEDEC
standards organization. With operating frequencies from 800 Mhz to 1600 Mhz,
DDR4 represents a significant advancement in performance with reduced power
usage compared to DDR3 technology.
"Based on our first generation
DDR3 analyzer, the Kibra 480 platform features new proprietary probing
technology designed to non-intrusively monitor the DDR4 bus", stated
Michael Romm, VP of product development at LeCroy Protocol Solutions Group.
"By incorporating our new custom silicon on a self-powered interposer
probe, we're able to provide instant signal lock - including reliable capture
of the DDR4 power-on sequence".
The Kibra 480 uses specialized trigger
logic to automatically identify over 65 JEDEC timing and command violations
across all ranks and banks simultaneously. This overcomes key limitations with
logic analyzer-based solutions which use state based triggering that is
complicated to setup and can only track two or three violations simultaneously.
In addition, the Kibra 480 highlights any errors in the timing display allowing
users to see and verify interoperability and compliance to the DDR4
specification.
"The LeCroy Kibra 480 offers an
economical way to increase test coverage and reduce time to market for
DDR-based memory systems", stated Roy Chestnut, Director of Peripherals
Product Group at LeCroy. "Because the analyzer can be used for today's
DDR3 and the next generation DDR4 standard by simply changing the interposer,
memory verification teams can leverage the LeCroy solution across multiple
design projects."
Upgraded software for the Kibra system
provides several enhancements including a new Bank State View which allows
users to visualize distribution of I/O operations across all banks.
Additionally, the ability to capture Serial Presence Detect (SPD) data lets
developers automatically discover the memory parameters used by system under
test. The Kibra 480 is also fully compatible with DDR3. LeCroy's Kibra offers
an economical way to increase test coverage with today's DDR3 technology. The
same system can also be extended to address the next generation DDR4 standard
by using different interposer probes. Customers can purchase the system with
interposer probe sets for DDR3, DDR4 or both. The LeCroy Kibra 480 will be
available in 2nd quarter of 2012.
