SunOS TOOLBOX PRODUCT ENGINEERING - COURSE #6056

Course Length

5 Days

Applicable Testers

All Quartet/Duo/Vista Series testers running the SunOS operating system.

Course Description

The class gives product engineers an understanding of the various debug and graphical tools on the Quartet/Duo/Vista test systems. Students learn which tools and commands are used for various types of failures. Included is a hardware overview of the system resources. Students are exposed to programming code covering various types of tests. Students also learn how to recognize run-time error problems.

Prerequisites

Knowledge of testing
Familiarity with basic UNIX commands

Course Outline

Day 1:

Driver and Comparator formats
PMU operations
Usage of the various rails (driver, PMU, and active loads)
Active loads
Software Subjects
Using on line manuals
How the debug hooks for logging and pausing are built into the elementals
How the pause, log, tstat and pstat commands work
Learn how to use some of the basic debug commands
Use the log, pause, pstat and tstat commands
Use gdebug to look at voltage and timing conditions
Use the FICM command to read, write, and invert pattern.

Day 2:

Specs and Device Troubleshooting
Overview of basic programming statements
How to debug AC, DC, and functional failures
How specs and patrefs are used and how to change them in debug
How to do Shmoo plots
How to use the scope and wave utilities
How the software/hardware does AC, DC, and functional tests
Examples of logical troubleshooting steps for various types of failures
Use the scope or wave tools

Analyze DC failures: PMU debug command
Analyze AC failures: appropriate log pause and TM commands
Create Shmoo plots
Troubleshooting
Work with basic commands and the debug tool
In this lab you will work with several kinds of failures. The lab will lead you through failures explaining which tools are most appropriate for particular kinds of failures.
