To ensure that the full power of your organization's knowledge is always leveraged, OptimalTest created the industry's first universal and independent testing scenario language, packaged it as OT-Rules and bundled it with OT-Mgr.

LEVERAGED KNOWLEDGE OT-Rules lets you leverage data and knowledge from all operations, including fab information (lithography, defects, particles, etc), e-test, and test results from all test sockets including "current" and "previous" information from lots, wafers, dice and neighbors of various types (proximity, geography, lithography exposure, touchdown).
QUALITY RULES The rule-set generator provides a structured approach to create rules with enforced validation, redundancy management, conflict resolution and prioritization. OT-Rules delivers the flexibility to define triggers, actions and exception criteria for any business scenario.
RULE MANIPULATION With OT-Rules, you can reuse, organize, bundle and publish rules. Copying rules from different devicesb and test programs for reuse availability is as easy as cut-and-paste with any conflicts immediately flagged for structured resolution. Rules are organized by devices, test sockets, and test programs. For more effective rules management, rules are easily bundled by product, test program, various test cells or cross-products and cross-modules -- to best serve your unique product needs. In addition, the Publisher of OT-Mgr enables easy bundling into rule sets, publishing them to OT-Box for real-time execution, OT-Post for off-line execution, or OT-Sim for simulation and analysis.
CHANGE MANAGEMENT The rule-set generator provides version control and management capabilities, enables multiple users to edit rules based on permission levels, and includes rule templates, best-known methods, and system defaults.
COPY-EXACTLY RESULTS OT-Rules allows centralized control of rule-set execution at fabrication sites with a seamless, silent release engine for new or updated rule sets.
KNOWLEDGE RETENTION By capturing rules that have been tested and validated over time, organizations capture accumulate experience and preserve knowledge regardless of staff turnover. The information is always available and visible to all current test professionals.
HARNESSED SIMULATION OT-Rules helps you maximize testing benefits by simulating the rules using historical testing data, prior to production. Together with OT-Sim, you gain an accurate understanding of the actual benefits and ROI of rule sets, delivering proof of concept for multiple what-if scenarios, and improving the quality and efficiency of published rule sets.
