7.1 OVERVIEW
COMPASS has four basic run modes: <Idle> , [Run Test] , [Run molbox] and [Run DUT] . Other than
<Idle> , which indicates that COMPASS is in a state in which configuration changes can be made, each of
these run modes is found in the [Run] menu on the main program. Before activating any of the run modes,
make sure that COMPASS has been configured to read the instruments required by the run mode
(see Section 10.1). With the exception of the tests in which all entries are manual, every run mode involves
continuous instrument polling to update data on the run screens. Adjust these screens as need to customize
the
COMPASS display (see Section 6.7). Sections 7.2 through 7.4 detail the COMPASS run modes.
7.2 [RUN], [RUN TEST]
This menu selection is used to select a DUT Definition execute a test defined by a Test Definition
(see Sections 8, 9). Test execution is divided into three sequential parts:
Test Initialization (see Section 7.2.1): Sets up the molbox interface, selects the DUT and Test
Definition to run and enters user ID. Many of the sequential steps of test initialization can be turned
ON or OFF using the
[Tools] , [Options] , [Initialize Test] tab (see Section 11.5).
Run Test (see Section 7.2.2): Runs purge (if included) and leak test (if included) followed by the
test flow points taking data at each point based on the test data selections. The details of how a test
runs are defined in the Test Definition (see Section 9). Certain aspects of how a test runs can be
customized using the
[Tools] , [Options] , [Run Test] and [End Test] tabs (see Sections 11.6, 11.7).
End Test (see Section 7.2.3): Presents the <Test Notes> screen to record test specific notes and
the <Test Complete> screen with various test conclusion options. Certain aspects of the test
conclusion can be customized using the [Tools] , [Options] , [End Test] tab (see Section 11.7).
7.2.1 TEST INITIALIZATION
Test initialization is the first part of test execution. With the exception of Step below, all the
sequential steps of test initialization can be turned ON or OFF using the
[Tools] , [Options] ,
[Initialize Test] tab (see Section 11.5). Test initialization proceeds as follows:
Initialize molbloc/molbox (see Section 7.2.1.1): If the reference specified in the
System Configuration is a molbox, COMPASS loads the molbloc information into memory
and determines which features are supported by the molbox. Depending on the current setup,
this may take several seconds. This is the only Test Initialization step that cannot be disabled.
Select starting molbloc channel (see Section 7.2.1.2): When a two channel molbox
reference is used, the initial molbloc channel can be selected if both channels have a
valid molbloc. If this step is turned OFF, the current molbloc channel is automatically used.
Select DUT (see Section 7.2.1.3): The DUT selection tool is presented allowing
selection of the DUT Definition to run. If this step is turned OFF, the screen is not shown and
the last DUT used is automatically selected.
