NEX-CPCI-A

The NEX-CPCI-A Bus Adapter provides clocking, setup, disassembly, and a quick convenient connection to the CompactPCI Bus. Supports 32-bit and 64-bit CompactPCI. Extender card design, uses Tek high density connectors. Supports +5V and +3.3V CompactPCI. Disassembly software is also included.

Disassembly: 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..

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.

Timing Analysis: By acquiring data in asynchronous mode on the Tektronix Logic Analyzer, high speed accurate timing measurements can be made of the CompactPCI Bus up to 2Ghz (500 ps) using a Tek TLA700 system..

Correlating Bus Activity: While the NEX-CPCI-A package is being used to monitor the CompactPCI 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.
