A "Package Exec" or "Test Executive" is used to customize the Operator's interface and manage the flow of the Tests that are required for production. When an Operator activates an Exec, the Testplan is compiled and run with live calibration data assembled from the auto-cal of each instrument, the one time calibration of the fixture and load boards and the annual NIST traceable system calibration. This process enables the accuracy and reliability found only on a Cassini. Package Execs are required for typical production use and can work with User App objects which pair a specific exec with a specific Short Cut version. Please reference the Product DocsTest Program Release Model - Release to Production to understand how the Exec fits into a typical production release cycle. The Package Exec maps Limits to Bins and datalog options are enabled. Execs are stored in guru with the "ri.sys.ObjClass = RiTestSessionDef" attribute and include a manifest that packages the RiTestplan when exported by Guru Browser (.gzp).



Activate Package Execs
To activate or launch a package exec, choose Test > Run Package Execs... to open the Select Testexec prompt. (See Figure 1) When logged on as "Operator", users can only see Test Execs with the Status attribute to "released". A user can also activate "released" Test Execs via touch screen by choosing System > Test Execs button from the main Cassini window. If User Apps are used, choose User Apps button. When logged in with a user with Development role, Execs can also be activated or edited from the Test Objects browser, see Product DocsUsing Test Objects Browser in Cassini App for details.

Edit Package Execs
Form the main Cassini window, choose Test > Edit Package Execs... to open the Select Testexec prompt. Filter and select an existing Package Exec from the list or click New to create a new one. Old versions of a selected plan can be accessed from the Version pull down menu. Device and Type can be used to filter the list of Testexecs shown.

New Package Exec
Package Execs can either be "Standard" for normal production or "Verification" used for tests the parts against averages. Verification policy excludes many options and does not include Bins or Datalog tabs. Multisite may also appear on this list to allow for various forms of multiple DUTs mapping to the same or different testplans, depending on implementation.


Editor "Exec" tab
Because the various tabs are related, options and tabs appear as the Package Exec is configured. The user may have to navigate to a tab, select "Add page", then navigate back to the first tab to access the newly created option. It will become obvious as features are explained.

Editing a Package Exec involves assigning the "Title" and selecting the "Device". Status is used to manage the release and version is used to distinguish different changes.
Select the Views and Options for display.


The Add Page and Del Page buttons are used to extend or contract the number of Testplans, Limits and Datalog tabs.
Press Ok button to save or save as if the Title changes and close and choose the Cancel button to abort any changes.
Since late 2019, an update changes the "Ok" button to "Save".

FieldMeaning / Intended Use
TitleName of this test exec. This will be the name displayed in the view to select and run the exec.
DeviceThe name of the device definition. This field is a drop-down list created from the Device definintions found in your Guru.
TypeThe supported types are "Production", "Retest", "Development", "Deprecated", and "Special". They are used to help organize test execs and describe their place in the testing lifecycle.
StatusThis includes values of "alpha", "beta", "released" as well as others. It describes the degree of completion of the exec
VersionYou may enter a number to represent the version of this exec. The number may be structured any way you choose, such as "1.00" or "v4.33.66"

Options:

OptionMeaning
Abort testing on FailureWill stop testing on first FAIL (exceeded limit for test). A similar setting can be set by the Test Plan Developer in the Testplan, or cna be set on the Testplan tab for a specific testplan, if multiple testplans are specified.
Auto-save Lot Summary reportCreates a PDF or Printed "Lot Summary" report. (See Product DocsInstalling PDF Writer in eComStation and Product DocsCleaning PDFs folder on EPC (Test Summary Reports) for more information)
Include tests in Lot Summary reportWARNING: Makes file size large. This includes every test result in the Lot Summary report. Ignored if above option is not included.
Simulate handler if absentAllows Exec to Run without a handler instead of Alerting operator.
Operate testexec manuallyEach "Start" will reset index count to 0. Operator must press Start for each DUT.
Location (x,y,subdie) for part indexReplaces DUT index number (1,2,3...) with the x,y,subdie location information provided by a Prober.


Views:

For very large lots, RI recommends disabling all views except for the Worksheet details window to avoid causing unexpected crash of the software due to memory constraints. The Worksheet details view is immune from these memory issues because it is running in a different process.

Worksheet Details Window: (See Database 'Product Docs', View 'All Documents', Document 'Worksheet Details from Cassini Test Exec or Test Plan Editor'Worksheet Details... for more information)



Pass/Fail Window: A sizable window that shows green for pass and red for fail. It can be seen from a long distance across the test floor.


Barchart of Hard bins: The graphical view of passing and failing bins shows a bar for each bin.


Barchart of Soft bins: The graphical view of passing and failing "soft" bins shows a bar for each bin.


Barchart of Tests: The graphical view of passing and failing tests shows a bar for each test.


Editor "Testplan" tab

Select a valid Test Plan from the "Name" field. Select Options, Site and Datalog values. To lock the testplan version, select "Do not update tesplan revision automatically" option. When releasing a new version of the testplan with the same Name, simply disable this option and save the exec. Once the evaluation is complete, select this option and save again to lock the testplan to the current version.



Use "Add Page" to add additional Test Plans.
note: Datalogs are added by clicking "Add Page" from the Datalog tab.

Editor "Limits" tab

Limits are used to set values of specific measurements of a Test Plan used to grade or sort the DUT into Handler Bins.

Clicking on the Limits tab below "Testplan" will allow you to select the "Base limit."



Details are accessed by clicking on the labeled tabs along the bottom of the Limits tab.
Use "Add Page" and "Del Page" to adjust the number of Limit pages available across the bottom.




Editor "Bins" tab

Soft and Hard bins are viewed from the "Bins" tab. Right Click on the column heading to access the Export and Import CSV options.



The "rank" value of the softbin determines which softbin is reported to the data log file when more than one softbin is triggered, usually by the Limits Map in the previous screen. For example, if a test called "Icc" fails to bin 3 with rank 200 and a test called "Pout" fails to bin 7 with a rank of 500, the system must make a choice if both tests fail. In this scenario the softbin with the highest "rank" will be reported to the data log file and the part will be placed in bin 7.

Hardbins are generally more limited in number than softbins. You may employ dozens or more softbins but your part handler likely has only a few physical hard bins. Note that the notion of "pass" and "fail" applies to the hardbins only. The softbins inherit the pass/fail setting of the hardbin they are mapped to. Like softbins, the hardbins may be either edited directly or saved to CSV for editing in a spreadsheet.


Editor "Datalog" tab

Datalog options include Format and the number of days to retain Detail and Summary files in Guru.
Use a Guru Agent to export the datalog to another location for processing.
