AN/AYK-14 Channel Monitor
System Overview
C-TAC Plus for AN/AYK-14 is an embedded system analyzer. It provides simultaneous Real-Time Non-Intrusive (RTNI) monitoring of all key points in the system. The monitoring is done on a completely non-intrusive basis without the injection of wait states or cycle stealing, and does not affect bus timing or message sequencing. C-TAC also provides time correlation of data across multiple processors, backplanes, and networks as well as system level evaluation in the operational environment.
Key Benefits
- Significant and affordable improvements in software quality.
- Dramatic cost savings in resolving software and integration problems.
- Data and event correlation and tracing across multiple processors and data busses.
- Greatly increases productivity in system integration and test.
- Ability to significantly shorten project schedules.
System Development Lifecycle
C-TAC Plus AN/AYK-14 Channel Monitor
The AN/AYK-14 Channel is designed to provide continuous RTNI monitoring for embedded computers in the AN/AYK-14 family. The monitoring is done on a completely non-intrusive basis, without the injection of wait states or cycle stealing. Software timing and sequencing are not affected by the monitoring function. Multiple channels can be placed in a single C-TAC Plus unit to simultaneously monitor additional processors or busses.
Channel Cross Triggering
The AN/AYK-14 Channel is able to cross trigger with other
channels (processors or buses) or with external
equipment.
Time-Correlation
All C-TAC Plus Channels use a common time stamp. This feature
allows time correlation of data collected from multiple
channels.
Common User Interface
Test setup, control, and post-run analysis are
accomplished with a symbolic user interface (Microsoft
Windows based), which significantly increases user
productivity.
Graphical Data Analysis
Graphical analysis software allows the user to plot
variable data and profile bus traffic quickly and easily.
High Volume Data Collection
The AN/AYK-14 Channel standard configuration provides
120 MBytes of real-time data storage with optional
extensions up to 1 Gigabyte.
AN/AYK-14(V) Versions Supported
All versions of the AN/AYK-14 are supported including
GPM, SCP, and VPM.
Modes of Operation
Image: Real-time display of up to 250 variables.
Log: Continuously recorded trace of user events to disk.
Burst recording rate at target speed. Sustained recording
rate of more than 40,000 events/second.
Snapshot: Recirculating trace of user events to memory;
delayed triggering for pre-, post- and center- trigger
placement.
Code Coverage: Maintains a scoreboard of code locations accessed during a test.
Events Detected
Access Type: Instruction, operand, I/O, read/write,
interrupt
Address Value: Up to 250 unique addresses or 83
ranges
Data Value: Signed/unsigned word and long word,
AN/AYK-14 single precision floating point formats; hex,
octal or decimal; =, ≠, <, >, ≤, ≥, in-range and out-of-range,
comparisons (true arithmetic ranges in target
representation format); multiple values for binary
encoded fields.
Actions On Events
Record: Records events in trace memory.
Site Transition: Change current state to next state. C-TAC Plus
can be configured to monitor events in 64 different user
definable states.
Trigger: Generates a trigger point to freeze the snapshot
trace. Freeze can be delayed for pre-, post- or center-triggering.
External Trigger: Asserts one of four external trigger
lines. Signals other channels, other C-TAC Plus units or other
equipment that a particular event occurred within the
system.
Time Sync: Asserts the external time sync line when the
event occurs.
Timer/Counters: Two timer/counters are available for
control of additional selected recording.
Variable Event Post-Run Analysis
Variable Plot: Linear or scatter plot of up to 6 variables as a function of time.
Procedure Event Post-Run Analysis
Process Timeline: Flow of program execution at the
procedure level. Graphical presentation of procedure
duration and sequencing.
Code Coverage: Indication of code and data areas
accessed during test
Auto Symbol Translator
- Optional feature automates test specification setup to significantly reduce data entry time and errors.
- Automates conversion of symbolic cross-reference information from the compiler toolset to the C-TAC Plus format.
- Conforms to MTASS/M symbol table formats.
- Automates update of addresses after software rebuild.
C-TAC Plus base unit
Configuration For The AN/AYK-14 Channel
- Event Detector and Acquisition Card (EDAC) detects and captures all event data specified by the user
- SCSI hard drive records event data captured by the EDAC
- Personality Interface Module (PIM) maps the AN/AYK-14 hardware and instruction set architecture for interface with the EDAC
- Probe Adaptor (PAD) provides a custom connection to the AN/AYK-14 and its signals for transmission to the PIM
