7 Introductio n Thank you for purchasing the FuturePlus Systems F S 2343 FBDI MM Interposer Logic Analyzer Probe. We think you will find the FS2343, along with your Agilent Technologies Logic Analyzer, a valuable tool for helping to chara cterize and d eb ug your FBDIMM- based systems. This Users G uide will prov ide the information you need to ins[...]

8 FS2343 Probe Description The FS2343 FBDIMM Interposer Probe is based on the “Lo gic An alyzer Interface (LAI) Mode” of the Advanced Memory Buffer chip used on Fully Buffered DIMMs. Thi s mode allows decoding of the Primary Southbound (from m emory control ler to FBDIMMs) Commands and Data as well as Secondary No rthbound Command s and Data fr[...]

9 Probe Technical Feature Su mmary • Quick and easy conne ction betwee n a 240 pin FBDIMM connector and Agilent 1690x Logic Analyzers. • Complete and accurate state analysi s of Primary South and Secon dary No rthbound FBDIMM traffic as seen by the AMB in LAI mode on the Interposer probe. • Integrated control of Advanced Memory Buffer Logic A[...]

10 Probe Set-up Probe overview The FS2343 Interposer probe uses an AMB device in “LAI” mod e and provides the appropriate FBDIMM conn ection s to an “inter posed” FBDIMM device for it to op erate within the memory bus. The LAI mode perform s 2 functions. First, it demultiplexes and decodes the NB and SB traffic into the frame ba sed informa[...]

11 The other orientation for the probe is wit h a 90 degree bend to either it’s front (A MB) or back side. There are right angle b ra ckets provid ed to kee p the probe in this position along with the associated nyl on hardware. It is our recomm endation that the interposed FBDIMM be placed in the probe before the prob e is bent over. This provid[...]

12 Signal Assignments on Prob e Pods There are signal connectio ns for up to 6 different logic analyzer adapter cable s (E5378A). This prov ides the user with some flexibilit y 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, SB and NB traffic together, etc. The 16753/4/[...]

13 FBDIMM Paddle Board Connector layout Software Requirements For state analysis you must have versio n 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 prob e through the 16753/4/5/6 or 16950 cards. Setting up the 1 69xx A nalyzer A CD containing the 16900 software is[...]

14 This is what the FS2343 probe u ser sho uld use to guide them in connecting ada pter cables to analyzer card pods. If the pod connections need to be chang ed, it can be done using the Edit Probes feature, which is shown below. The Refe rence De sig nator field should be J9 through J15 from the paddle card. The next step is to select on the right[...]

15 Configuration File Labels The configuration files provided with the probe software have a number of labels defined that are useful in providing rapid identific ation of sampling position, DRAM, an d Channel Command activity in the state listing. They c an also be use d as triggers for the logic analyzer. These labels include: Sampling labels The[...]

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 chan nel sh ould transition from the L0 state to the L0s state for exactly 42 frames. The L0 state is the stat[...]

17 Symbols Terms used in the FBDIMM proto col are def ined under labels that are referred to as symbols. Symbols can be used in d efining triggers or for use in default store qualifications. Below is a list of labels with the symbols define d. When using a label for which symbols are defined, change the hex property to sym to display the symbol rep[...]

If the Southbound or Northboun d is in failover mode, the preference s mu st be set accordingly. If the Northbound side is in failover the user m ust select which lane has failed in order for the decoder to[...]

21 SM (SMBus) Contro l Paddle card Settings The FS2343 probe is designed so that AMB/LA I device control can be either from the 16900 logic analyzer and t he Probe Control applic ation software resid ent there, or from another FS2343 probe (slave mode). This feature is controlled by means of a 6 position switch on the probe pad dle card near the lo[...]

22 Event Bus Cabling The Event Bus bits, Evbus[0:3], from other probes can be daisy chained acro ss m ultiple probes in order to provide cro s s probe cont rol of other probes. There are 2 EV cable connectors on each probe and both connectors are wired in parallel so that eithe r can be used. Additionally, the probe has termination sensing circuitr[...]

23 Setup The Set-up screen provides control ove r basic probe use. • The probe Configuration se tup button all ows the user to select when they want to set up the parameters within the AMB. The choices are al way s after link training, before link training only when n eede d, or always before link training. If all you are interested in is data af[...]

24 SB Commands This allows Match or Mask control over any 3 Command pattern s e ntered by the user in either hex or binary format. Furthermore, each of 3 pat terns 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 user to set 3 different command patte rns along [...]

25 Store Qualificat ion This section controls the op eration of the Qual Flag, Qual Stop Delay, and Qual Period Delay. It allows the user to select from 32 di fferent events for the definition of Qual Start and Qual Stop. These settings control the st ate of the Store_qual flag for non -filtered frames. The Store_qual flag in the configurat ion fil[...]

26 Trigger Events This capability allows the Probe user to define each of the AMB’s logic a nalyzer Triggers [0:10] to be set to one of 32 different event cond itions seen by the AMB. It is important to note that not all LAITrig[0:10] signals are available to the logic ana lyzer. Thi s is dependent on the configurat ion file loade d and the pod c[...]
