NEX-PCI32SWL & NEX-PCI3264SWL
The NEX-PCI32SWL and NEX-PCI3264SWL product is software only. It provides clocking, setup, and disassembly. NEX-PCI32SWL supports 32-bit PCI data bus applications. NEX-PCI3264SWL supports 32 and 64-bit PCI data bus applications. NEX-PCISWL Data Sheet in PDF Format. A manual is available for immediate download NEX-PCISWL Manual. It contains additional information including the required pinout used in layout.
Disassembly: All Configuration accesses are decoded. Class, Sub-Class, and Prog. I/F information is displayed in hexadecimal form, but then is further decoded to tell the user exactly what Class and Sub-Class of device is being accessed (Mass Storage, Display, Network, etc.). The command and status registers are decoded, the bit-level information displayed in easily understood form. Disassembly Screen Shot #1 is a screen shot showing both of these features, with Disassembly Screen Shot #2 showing the read from the status register and the setting of a control bit through a Configuration Write.
Invalid data bytes are dashed out during valid Data Cycles.
There are also 3 Select Fields in the Define Format menu of the Disassembly Display. These fields permit choosing whether I/O, Memory, and Configuration Cycles are highlighted or displayed normally. Changing the Display Format from Hardware to Software, Control Flow, or Subroutine will suppress the display of those cycles that are set to Normal mode. This permits focusing in on information that is of interest. Display Format Screen Shot shows the Define Format menu window.
Timing Analysis: By acquiring data in asynchronous or transitional mode with a Tektronix Logic Analyzer, high-speed accurate timing measurements can be made of the PCI Bus.
Correlating Bus Activity: While the NEX-PCI32SWL or NEX-PCI3264SWL package and appropriate adapter card is being used to monitor the PCI backplane activity, another acquisition module can be used to monitor activity elsewhere in the system. The results of the two acquisitions can be correlated in time to determine the sequence of actions that occurred. For instance, the system microprocessor could be monitored and correlated with bus activity to verify the proper response to an external interrupt condition.
