RI GURU - Portable Test Plan Environment

Guru is a redundant, distributed, and secure object database designed specifically for semiconductor automated testing.

Guru Operating System & Network Independent

• Guru Clients for OS/2, Windows, Linux (Java Supported OS)
• TCP/IP standard network protocols allow for easy integration into existing network (DHCP)
• Internal firewall prevents unauthorized access and significantly reduces network vulnerability

Guru Programming Language Neutral

• ASCII based storage formats for data for easy interoperability (i.e. for Analytics software)
• Application programming interfaces (API) for Java, Smalltalk, Jython - the Python like scripting language for Java

Guru Automatic Backup and Recovery

• File version history is available to easily revert to any previously saved state
• Guru servers have automatic recovery so no configuration is needed when replacing hardware
• Redundant, hot-swap guru utility server nodes allow for quick on-site replacement of failed hardware

Guru Data logging

• near real time data logging with STDF snapshots that does not impact test performance
• aggregating - collection agent collects test data from all test systems
• translates and uploads to other resources (files, databases, ftp) *custom engineering required
• non-RI data importing agent for standardization across the test floor - STDF *custom engineering required

Guru Testplan Distribution and Management (version control)

• single point of release controls production floor reliability
• staged release workflow (alpha, beta, released)
• a Testplan can be locked to allow absolute version control on every file in the environment
• snapshot of complete environment tied to a released test plan with UserApps

Guru True Global Distribution System - hierarchical storage system

• automated software updates
• automatically retrieves latest version of files
• policy based file filtering based on the connecting client Guru is used to prevent unauthorized users from seeing protected files

Guru Usage Accounting and auditing

• summary of event log, logging testers usage
• OEE monitoring for usage audit using standard log files
• near real time event logging
• custom system error reporting agent (email), Java / Jython scripting language *custom engineering required

Guru Test House Enabled

• full public/private encryption key authentication for remote connections
• all files are digitally signed and authenticated to prevent corruption
• all files can be optionally encrypted with 1024-bit Blowfish encryption algorithm
• policy based security to keep data separated

*custom engineering required - these features requires software customization's based on customer requirements

Hardware

• Fully integrated appliance - utility hardware
• Enterprise Guru Server is a pair (or more) of cloned servers that run only RI Guru
• Facility must provide a Standard EIA rack (2U to 8U) and A/C Uninterruptible Power Supply (UPS)
• There are many reasons to not run other applications on guru hardware:
• Guru performance is impacted
• no supported user interface for installing applications
• other applications can compromise reliability and security of operating system
• OS environment customization can not be allowed
• there is no failover protection or backup and restore abilities for other applications
• tuned operating system for Guru
• setting system clock can cause failure
• all service is performed via a exchange of hardware, any customization can not be made by RI
• Additional space is available for non-RI application servers.
• Optional rack mounted terminal and KVM may provide user interface to non-RI hardware
• Virtual Machine hosting possible (unsupported) -- system clock UTC, can cause failures when not correct.
