LeCroy claims first DDR4 bus and timing analyzer
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.
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.
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. Kibra 480 will be available in the 2nd quarter of 2012.
