7 Introduction Thank you for purchasing the FuturePlus Systems FS2343 FBDIMM Interposer Logic Analyzer Probe. We think you will find the FS2343, along with your Agilent Technologies Logic Analyzer, a valuable tool for helping to characterize and debug your FBDIMM-based systems. This Users Guide will...

9 Probe Technical Feature Summary • Quick and easy connection between a 240 pin FBDIMM connector and Agilent 1690x Logic Analyzers. • Complete and accurate state analysis of Primary South and Secondary Northbound FBDIMM traffic as seen by the AMB in LAI mode on the Interposer probe. • Integrated con...

11 The other orientation for the probe is with a 90 degree bend to either it’s front (AMB) or back side. There are right angle brackets provided to keep the probe in this position along with the associated nylon hardware. It is our recommendation that the interposed FBDIMM be placed in the probe bef...

12 Signal Assignments on Probe Pods There are signal connections for up to 6 different logic analyzer adapter cables (E5378A). This provides the user with some flexibility in terms of which signals they connect to based on the type of analysis that is needed, e.g. SB or NB only, all trigger events, ...

13 FBDIMM Paddle Board Connector layout Software Requirements For state analysis you must have version A.02.99.00 or later Agilent OS installed on the 1690x frame. Version A.02.99.00 contains the capability for SMBus control of the probe through the 16753/4/5/6 or 16950 cards. Setting up the 169xx A...

15 Configuration File Labels The configuration files provided with the probe software have a number of labels defined that are useful in providing rapid identification of sampling position, DRAM, and Channel Command activity in the state listing. They can also be used as triggers for the logic analy...

16 TID – single Transaction identifier bit, used in Write Config. Register Channel Command. SD - Status delay, 2 bit field used in Sync command. Allows return status data to be delayed by up to 3 frames. EL0s - The EL0s bit indicates the channel should transition from the L0 state to the L0s state f...

17 Symbols Terms used in the FBDIMM protocol are defined under labels that are referred to as symbols. Symbols can be used in defining triggers or for use in default store qualifications. Below is a list of labels with the symbols defined. When using a label for which symbols are defined, change the...

19 Example using symbol “Activate” in a trigger Preferences The Preferences option is used to set the protocol decoder for failover mode. If the Southbound or Northbound is in failover mode, the preferences must be set accordingly. If the Northbound side is in failover the user must select which lan...

21 SM (SMBus) Control Paddle card Settings The FS2343 probe is designed so that AMB/LAI device control can be either from the 16900 logic analyzer and the Probe Control application software resident there, or from another FS2343 probe (slave mode). This feature is controlled by means of a 6 position...

22 Event Bus Cabling The Event Bus bits, Evbus[0:3], from other probes can be daisy chained across multiple probes in order to provide cross probe control of other probes. There are 2 EV cable connectors on each probe and both connectors are wired in parallel so that either can be used. Additionally...

23 Setup The Set-up screen provides control over basic probe use. • The probe Configuration setup button allows the user to select when they want to set up the parameters within the AMB. The choices are always after link training, before link training only when needed, or always before link training...

24 SB Commands This allows Match or Mask control over any 3 Command patterns entered by the user in either hex or binary format. Furthermore, each of 3 patterns can be searched for in either Command Slot A, B or C, or all three patterns in all 3 Command Slots. The mask and match feature allows the u...

25 Store Qualification This section controls the operation of the Qual Flag, Qual Stop Delay, and Qual Period Delay. It allows the user to select from 32 different events for the definition of Qual Start and Qual Stop. These settings control the state of the Store_qual flag for non-filtered frames. ...

26 Trigger Events This capability allows the Probe user to define each of the AMB’s logic analyzer Triggers [0:10] to be set to one of 32 different event conditions seen by the AMB. It is important to note that not all LAITrig[0:10] signals are available to the logic analyzer. This is dependent on t...

27 Event Bus This feature controls the operation of the Event Bus signals EV[0:3] which can be used for communication and triggering between probes in an FBDIMM Channel.

28 State Analysis Operation For proper state analysis the user must choose the correct configuration file to load depending on what type of analysis is desired, such as analyzing both Northbound and Southbound activity or just one direction. The list of configuration files provided is on page 12. Lo...

30 State Display Offline Analysis Offline analysis allows a user to be able to analyze a trace offline at a PC so it frees up the analyzer for another person to use the analyzer to capture data. If you have already used the FBDIMM Protocol Decoder license that was included with your package on a 168...

33 Appendix FS2343 Paddle Signal to Logic Analyzer Connector and Channel Mapping The following table shows how the FS2343 Probe connects FBDIMM AMB signals to the logic analyzer pods and channels through the 100 pin Samtec connectors. Note that the configuration files described earlier use various c...

45 General Information This chapter provides additional reference information including the characteristics and signal connections for the FS2343 FBDIMM Interposer Probe. The following operating characteristics are not specifications, but are typical operating characteristics. Probe Connection 240 p...
