NEX-SRIO (Serial RapidIO)

Serial RapidIO (SRIO) Preprocessor & Software

New! TLA7BB4 support cuts Tektronix hardware requirements in half allowing for full-duplex acquisition using one 136-channel TLA7BB4 acquisition module.

New! Support available for both Tektronix P6960 and P6860 probes.

NEX-SRIO consists of a hardware preprocessor box, setup software and TLA disassembly software. NEX-SRIO can capture two datapaths (usually one transmit and one receive) running at 1.25-, 2.5-, or 3.125-Gbaud in 1x or 4x Mode.

A topological view of connection, including the system-under-test and the Tektronix Logic Analyzer are shown below. The flow of Serial Rapid IO (SRIO) traffic can be seen through points A-D, in red. Points A and B carry the serial data to the preprocessor, where it is deserialized and analyzed . The deserialized data is then sent to the TLA for disassembly though points C and D. Note that the USB connection (point E) is not part of the SRIO traffic flow and is used only for setting up the preprocessor.

NEX-SRIO (Serial RapidIO) Dataflow
Path A
Connection between the system-under-test and the probe. This can be an NEX-MIDBUS probe or two to eight NEX-SERIALPROBE probes. Please call for the Probing Design Guide for NEX-SRIO document for more detailed information.
Path B
The probe(s) are connected to the preprocessor on a channel by channel basis.
Path C
The preprocessor uses P6960 or P6860 probes to send the deserialized data to the logic analyzer.
Path D
The P6960 or P6860 probes connect to the logic analyzer. The logic analyzer then triggers, stores and disassembles, and displays the data for the user.
Path E
The USB connection is used to transfer setup information to and from the preprocessor.

1 Datapath (1/2 Duplex) Support

A TLA7000 equipped with one (1) TLA7BB4 acquisition module or a TLA700 equipped with one (1), 450MHz state speed, acquisition module (TLA7xx2/3/4) is required for a single SRIO datapath (1/2 duplex). Two (2) P6960 or two (2) P6860 probes are also required. Either an NEX-MIDBUS probe or a quantity of NEX-SERIALPROBEs is also required.

2 Datapaths (Full Duplex) Support

A TLA7000 equipped with one (1), TLA7BB4 acquisition module or a TLA700 equipped with two (2) TLA7Ax2/3/4, 450MHz state speed, acquisition modules is required for two SRIO datapaths (full duplex). Also required are four (4) P6960 probes or four (4) P6860 probes. Either an NEX-MIDBUS probe or a quantity of NEX-SERIALPROBEs is also required.
