Introduction
Definitions
Thank you for purchasing the FuturePlus Systems FS2331 DDR SDRAM Logic Analyzer Probe. We believe you will find the FS2331, along with your Agilent Technologies Logic Analyzer, a valuable tool for helping to characterize and debug your DDR-based systems. This User Manual will provide the information you need to install, configure, and use the FS2331 Probe. If you have any questions about this User Manual or use of the FS2331 Probe, please contact FuturePlus Systems Corporation.
DDR Bus Speed
This document will use the following definitions when describing DDR memory speeds:
PC1600 or 200Mhz describes DDR DIMMs running at a clock rate on the memory
bus differential clock of 100Mhz, which results in a data transfer rate of 200Mhz (or
1.6 GBytes/sec throughput). DDR commands are issued at a 100Mhz rate. PC2100 or 266Mhz describes DDR DIMMs running at a clock rate on the memory
bus differential clock of 133Mhz, which results in a data transfer rate of 266Mhz (or
2.1 GBytes/sec throughput). DDR commands are issued at a 133Mhz rate. PC2700 or 333Mhz describes DDR DIMMs running at a clock rate on the memory
bus differential clock of 167Mhz, which results in a data transfer rate of 333Mhz (or
2.7 GBytes/sec throughput). DDR commands are issued at a 167Mhz rate.
Probe Cable, Connector Numbering
The FS2331 has 4 connectors that connect to the logic analyzer through 4 logic analyzer adapter cables. These connectors are described as "J1" through "J4". When "Pod <n>" is referenced in this manual it is the logic analyzer cable end that is plugged into "J <n>" of the FS2331 per figure on page 7.
Logic Analyzer Modules
"Module" - A set of logic analyzer cards that have been configured (via internal cables connecting the cards) to operate as a single logic analyzer whose total available channels is the sum of the channels on each card. A trigger within a module can be specified using all of the channels of that module. Each module may be further broken up into "Machines”. A single module may not extend beyond a single 5 card frame.
Logic Analyzer Machines
"Machine" - A set of logic analyzer pods from a logic analyzer module grouped together to operate as a single state or timing analyzer. Each logic analyzer module may be partitioned into up to two independent "Machines" (either two state machines, or a state and a timing machine), and the pods of a module may be assigned freely to either machine. Each state analyzer machine has its own state clock. Turbo mode (333Mhz for 1671x, 400Mhz for 16750/1/2, 600Mhz for 16753/4/5 cards) operation restricts a module to having only one machine. Cross triggering between modules or machines is done via the Intermodule Bus or via the Flag bits, which will communicate across a 16700 frame and its expander, or across multiple frames if the Multiframe product is used.

Probe Design
This probe uses discrete ECL logic in order to operate at the speed necessary to provide DDR333 signal decode. Because ECL logic operates in linear mode it dissipates more heat than other logic designs.
BE ADVISED – THE PROBE IS HOT TO THE TOUCH. . If the user believes that the
FS2331’s temperature is above 80°C, then a fan should be used to provide additional cooling.
In order to support source synchronous data capture the FS2331 DDR probe monitors the clock (CK0/CK0n) and control (DQS0, CAS, RAS, WE, S0:3) signals on the DIMM connector where the probe is inserted. In some cases the probe may also need access to the chip select signals for other DIMM slots to enable source synchronous data capture. There may be situations where these signals are not provided by the target system. For instance, some systems may turn off CK0 to slots where no DIMM module is detected. In other systems, the unique Chip Select signals for each DIMM may need to be connected to the probe.
If there is any reason to suspect that these conditions are present on your target, contact FuturePlus Technical Support.
State Clock Generation
The FS2331 DDR probe uses one logic analyzer machine to capture DDR commands (using the common clock CK0) and another machine to capture DDR burst data (using the source synchronous strobe DQS0). The logic analyzer automatically combines the trace data from both machines into a single time correlated trace of DDR bus activity. The circuitry on the probe is used to generate the proper state analysis clocks for the command and data analysis machines.
DDR Commands
Since the DDR bus global clock is differential it is converted to a single ended clock for the analyzer using a differential line receiver. DDR Commands are sampled on the rising edge of this clock.
DDR Data
The FS2331 supports state analysis of DDR busses by combining a specially processed version of the DQS0 strobe with Agilent's Eye Finder technology. This allows the analyzer/probe combination to accurately locate (much as a DDR controller chipset does) the read and write data valid windows for each data bus signal and sample the data at the proper time for reliable state analysis.
Each DDR bus implementation will have different timing due to trace length variation on the motherboard, variations in bus loading for each DIMM configuration, and sensitivity to dynamic factors such as crosstalk or simultaneous switching noise. Therefore, the precise position of the DDR data eye will vary from system to system and even within a system as DIMM configurations or data access patterns change. To achieve the most reliable data capture the location of the data eye must be determined on a given system using worst case data access patterns. The logic analyzers Eye Finder feature is used to measure the location of the eye for each data signal over millions of burst cycles and so achieve the most reliable state capture. By using the proper stimulus when running Eye Finder the worst-case data valid window boundaries are found and the analyzer is set to sample data at the center of the actual data valid window of each signal for each specific DDR implementation and DIMM configuration.
10
Because strobe edges are centered on the data valid window for writes, and straddle it for reads, the analyzer cannot simply use the raw DQS0 to sample data. If it did, then even in the ideal case, only half of the data valid window would be usable. In practice, it would almost completely disappear. To deal with this, the DDR Probe adjusts the timing of DQS0 before sending it to the analyzer state clock input by delaying it a fixed amount for reads. This is done using a socketed delay line, which is set at the factory and should be sufficient. If EyeFinder results show good eyes when the probe is set to pass Reads only and Writes only (SW #6 off), but the eyes are significantly reduced when the probe passes BOTH Reads and Writes (SW #6 on), then the delay value on the probe may need adjustment. The calibration procedure documented in this User Manual describes how to set the probe delay line and analyzer sample position for reliable state analysis operation.
Because the strobes are tristated between bursts their logic value is undefined. Some systems will terminate the DDR bus to a voltage close to the Vref voltage, causing the strobes to sit right at the switching threshold. During read bursts, because read data (and strobes) are actually not valid until the reflected wave reaches the probe, DQS0 may also spend a significant amount of time at Voh/2 (close to Vref) between arrival of the incident wave and the reflected wave. Therefore, simply comparing the DQS0 signal to Vref will result in spurious analysis clocks being generated between bursts and during read bursts. The DDR probe deals with these factors by recognizing valid DQS0 edges only when they are closer to Vih than Vref as well as by inhibiting the state clock between bursts. In actual operation enough noise immunity is added by the special DQS0 receiver circuit to eliminate almost all spurious data strobes without inhibiting the clock.
All of these factors combine to add jitter to the read and write strobes sensed by the DDR probe. This jitter reduces the data valid window available to the logic analyzer. In some systems and DIMM configurations that have tight bus timing this may make it difficult to find an appropriate point to sample state data. This is especially true for read bursts that usually have more complex strobe and data waveforms. Eye Finder will measure the data valid window available to the analyzer for each signal and clearly indicate which ones may have difficulty reliably sampling state data given actual DDR bus timing.

Probe Pod Assignment
The FS2331 DDR Probe uses 8 pods. Two are used to capture traffic on the DDR Command bus, and 6 are used for the Data bus, strobes, check bits, masks, and Serial Presence Detect signals. The signals are mapped to pods as follows:
Pod Clock Domain

Data (2x) (Spare – J11on JCLK), SCL, DQS14-16, DQ44-
47, DQ52-55, DQ60-63.
The overlap in the bit ranges for signals between pods occurs because the bits are assigned to pods in the order that they appear physically on the DIMM connector, which is not strictly in logical bit order. This allows the probe layout to better match stub lengths among all DQxx signals.
See the Appendix for a detailed list of how Logic Analyzer Channels are mapped to signals and DIMM pins.

Function
When SW4 is closed the Buffered
Command Clock signal to the logic
analyzer is passed only when there is a
valid (low) S0:3 signal to the probe. This
is useful for EyeScan of Command
signals.
SW5 is dependent on SW6. When SW6
is open, SW5 open will pass a state
clock signal only during a Read
command. SW5 closed will pass only
on a Write.
When SW6 is closed, the probe
provides a state clock during both
Reads and Writes. When SW6 is open
it engages SW5.
13
Logic Analyzer Signal Threshold Voltage Settings
Threshold voltage settings are set at SSTL-2 levels (1.25 V) for all pods in the format specification of the analyzer. The user may have to adjust this setting for optimal performance for their specific target. Eye Finder and/or EyeScan may have to be run to find out if adjusting the threshold levels will optimize the data valid windows.
Connecting the Probe to the Logic Analyzer
The FS2331 requires two or three logic analyzer cards depending on the DIMM bus speed, whether state or timing measurements are being used, and the type of logic analyzer card being used. For timing measurements only two cards (configured as a single logic analysis module using one analyzer “machine”) are necessary.
Whether using a 2 card or a 3 card configuration, the cards must all be the same model. Because the DDR bus clocks commands on one clock and strobes data on a separate
set of strobes, state analysis requires that two separate analyzer “machines” be used, one for Commands and one for Data. For 200Mhz operation 16750/1/2 (200/400Mhz) cards provide sufficient speed in their normal mode to capture Data and Commands, so a two card module configured into one machine for Commands and one for Data is sufficient. When running at higher speeds, the analyzer capturing Data bursts may need to be configured to run in its high speed (Turbo) mode, which requires it to be in a module of its own. A third card configured as a separate module is then needed to capture and trigger on DDR Commands. Six pods of the data module are used for data capture (two are reserved for time tags). However, only two pods in the module used to capture DDR Commands are used for Command capture. The other two may be used for any other purpose (such as to probe chip select signals of a separate DDR memory bank). If 16760 cards are being used for both Command and Data analyzers, then 5 cards are required. One card for commands, 4 cards for data. The reason 4 cards are required for data, is because the cards must be run in 400 Mb/s mode with time tags turned on for time correlation with the Command machine; with time tags turned on 1 pod per machine cannot be used. With 4 cards connected together as one machine with time tags on at 400 Mb/s or greater there are 7 pods out of 8 available to use. Without the 4th card only 5 pods would be available, when 6 are needed. A summary of this information appears on the following table.
Triggering on a combination of commands and data is accomplished by using the Intermodule Bus, which sends an "Arm" signal between all analyzer modules. You can also use the "Flag" bits to communicate between the DDR Command and DDR Data triggering systems.
Connecting Power to the FS2331 Probe
After connecting the probe to the logic analyzer cables, insert it into the target system. After the probe is in the target system and connected to the logic analyzer, connect the
external power supply provided with the FS2331 to the probe. Do this step last and only use the power supply provided with the FS2331.
14
Card Requirements for PC2700 Systems
In order to insure that the FS2331 and the logic analyzer work properly with PC2700 systems it is recommended that the 16753/4/5/6 cards be used when probing at DDR rates of 333Mhz or greater. This recommendation is based on several factors.
First, the setup and hold requirement for PC2700 is specified as a minimum of 900 ps. Some combination of target systems and DIMMs may operate with a setup and hold time greater than this, but to insure accurate data capture the higher performance of the 16753/4/5/6 cards is needed.
Second, the loading on the target system presented by the 16753/4/5/6 combined with the E5378A adapter cables is significantly lower than the loading of the 1671x or 16750/1/2 and the E5385A cables. This may affect target system performance or measurements.

Software Requirements
System Software
The FS2331 Probe requires version A.02.70.00 (or later) of the 16700 System Operating Software. You can check to see if you already have the correct version by opening the “System Administration” dialog and selecting the “Show Version” button. If you do not have the correct version then you must update your system software. Please consult 16700 system documentation for the SW update procedure.
Setting up the 167xx Analyzer
The floppy disk(s) supplied with the FS2331 DDR Probe contains the software required to operate the FS2331. Install the Inverse Assembler and Configuration files from the floppy using the 16700 software installation procedure. This will install an inverse assembler called “IFS2331E” in the standard location for inverse assemblers, and will install several configuration files in the /logic/configs/FuturePlus/FS2331 directory that allow you to easily configure the analyzer for timing or state operation with the FS2331. See the sections below for information on which configuration file to use for your application.
Setting up the 169xx Analyzer
A CD containing the 16900 software is included in the FS2331 package. The CD contains a setup file that will automatically install the configuration files and protocol decoder onto a PC containing the 16900 operating system or onto a 16900 analyzer itself.
To install the software simply double click the .exe file on the CD containing the 16900 software. After accepting the license agreement the software should install within a couple of minutes.
169xx Licensing
Once the software has been successfully installed you must license the software. Please refer to the entitlement certificate for instructions on licensing the software. The software can only be installed on one machine. If you need to install the software on more than one machine you must contact the FuturePlus sales department to purchase additional licenses.
Loading 169xx configuration files and define probes feature
When the software has been licensed you should be ready to load a configuration file. You can access the configuration files by clicking on the folder that was placed on the desktop. When you click on the folder it should open up to display all the configuration files to choose from. If you put your mouse cursor on the name of the file a description will appear telling you what the setup consists of, once you choose the configuration file that is appropriate for your configuration the 169xx operating system should execute. The protocol decoder automatically loads when the configuration file is loaded. If the decoder does not load, you may load it by selecting tools from the menu bar at the top of the screen and select the decoder from the list.
After loading the configuration file of choice, go into the format specification of the configuration by choosing Setup from the menu bar and then selecting Bus/Signal in the drop down menu. When the format specification appears press Define Probes at the bottom of the screen. The Define Probes feature will describe how to hook the analyzer cards to the connections on the target. The following figure shows what the Define Probes screen looks like. The figure below may differ from your display; this is an example of how the display looks in general.
