This TUG paper will discuss two applications: Teradyne Result Viewer (TRV) & Graphical Flow Results.

Teradyne Result Viewer (TRV): A newly developed application, which is a Data Application Server (DAS) that receives data from a tester through Tester Event Messaging for Semiconductors (TEMS) protocol. With TEMS protocol, TRV can run locally on the tester, or remotely on another PC. TRV allows user to view test results real time while test program is running. TRV performs statistical data analysis (CPK values, Standard Deviation, etc.) on the fly when new test results come in. TRV shows data in tabular form, which supports filtering, sorting, grouping, etc. User can also view the data with different type of charts (test result trend chart, histogram and boxplot). TRV supports exporting test result data to csv files, so user can perform result analysis later.TRV also displays real time binning and yield information, which supports tabular view for hard and soft bins, per site yield and overall yield. User can also view binning distribution, per site yield with pareto charts.TRV will be an useful tool for test/product engineers, such as troubleshooting test/product issues by utilizing statistical data and charts.

Graphical Flow Results: The new requirements and UI for graphically showing test results in IG-XL for debug runs will be described. The goal is to enable the test engineer to quickly identify and debug failing tests and sites. Test rows on the flow table will be colored red or green to indicate if the test passed or failed. The sheet selector will have a new tab that shows a hierarchical view of the flow tables that are also colored red or green based on the status of the tests on each sheet.
The sheet selector will also have a site selector that lets the user see which tests failed by site(s). Test program navigation from the sheet selector will be enhanced to quickly jump to and navigate between failing tests.
