Module Reduction (MR) Technology™

Qualified Analysis - Half the Hardware

Nexus Technology's Module Reduction (MR) Technology™

Before module reduction, the Tektronix logic analyzer required four TLA7BB4 logic analyzer modules for full analysis of DDR3 at speeds of DDR3-1600 and DDR3-1867 and two TLA7BB4 modules for full analysis of DDR3 at speeds of DDR3-1333 and slower. With the introduction of module reduction techniques, the number of logic analyzer modules was reduced from four to two for DDR3-1600 & DDR3-1867 and from two to one for DDR3-1333 and slower. This reduction is derived completely in software by customizing the analyzer's internal resources in a unique and proprietary way. All logic analyzer features available to the end user are completely preserved with no feature limitations. The following facts on software module reduction may be of interest.

Facts About Software Module Reduction (MR) Technology™

 

  1. Module reduction software is completely transparent to the user. There are absolutely no special settings or choices required to use module reduction. Data is displayed correctly without any added intervention by the user.
  2. SODIMM acquisition is NEVER effected by module reduction. Data is acquired and viewable - simultaneously - from each rank for every possible state of the DDR3 bus. To put it another way, there is absolutely no penalty for using module reduction with your SODIMM target.
  3. DIMM acquisition is NEVER effected by module reduction for single and dual rank DIMMs. Just as with the SODIMMs, data is acquired and viewable - simultaneously - for each rank. Again, there is absolutely no penalty for using module reduction with your single or dual rank targets and DIMMs.
  4. Are you working with power down states in a quad rank DDR3-1600/1867 DIMM? Probably not, but if you are, please give us a call as there are unique challenges in this environment.
  5. No qualifier sideband signals are required which would otherwise force double-probing and increase the load on the DDR3 target.
  6. If you already own a Nexus interposer, module reduction can be implemented with a software update.

Nexus Technology has a family of products for your DDR3 debug application offering high speed connection and data analysis. From DDR3 interposers, NEXVu validation DIMMs (VDIMMS), embedded supports, chip interposers, to protocol violation software, Nexus Technology has the DDR3 product line to fully support your needs.
