18.1 OVERVIEW
Data files (*.dat) are the files created by COMPASS to store the data relating to a test run on a DUT using
[Run Test] (see Section 7.2). Data files can be viewed, edited, printed and made into custom reports all
within COMPASS . Data files have also been designed to be easily exported to third party applications,
such as spreadsheets or instrument management software.
18.2 DATA FILE CREATION
At the beginning of a test run (see Section 7.2), a Data File (*.dat) is created. This file contains all the
details on the test (reference information, DUT information, test information) and test data is logged to it
as the test runs. If a test is aborted before test conclusion is reached, the
[Tools] , [Options] , [Data File]
tab setting (see Section 11.8) determines whether COMPASS queries the operator as to whether to keep
or delete the partial Data File or the Data File is automatically deleted by COMPASS .
18.3 NAMING AND STORING DATA FILES
Data files are named and stored automatically. The default directory for COMPASS Data Files is
“\data\ DUTIDinfo \*.dat”. The “DUTIDinfo” sub-directory is created automatically by COMPASS using the
DUT information selected on the [Tools] , [Options] , [Data File] tab (see Section 11.8). By default, the
DUT serial number is used (specified in the DUT Definition, see Section 8.5.2). The DUT based
sub-directories are automatically created by
COMPASS at the designated location.
The automated Data File name follows one of two formats determined by the [Tools] , [Options] , [Data
File] tab preference (see Section 8.5.2). Realize that this is a default file name and that all complete Data
Files can be renamed using the <Re-Name> option on the <Test Complete> dialog (see Section 7.2.3).
Long Data File naming is used by default. This name is formatted as YYYY_ddd_rrr where:
•
YYYY: Is the four digit year.
•
ddd: Is the three digit day of the year (Julian date). e.g., 001 for January 1 and 365 for December 31.
•
rrr: Represents the test run number on the DUT being tested for the current day. This indicator
increments from 000 to 999.
Short Data File naming displays as YYdddrrr where:
•
YY: Is the two digit year.
•
ddd: Is the three digit day of the year (Julian date). e.g., 001 for January 1 and 365 for December 31.
•
rrr: Represents the test run number on the DUT being tested for the current day. This indicator
increments from 000 to 999.
COMPASS’s automatic naming convention for Data Files makes it possible for two *.dat files to have
the same name. However, the two files will always be stored in different directories since they would
have to be for DUTs with different identifications. To avoid conflicts or accidental overwrites when
moving Data Files to new locations, the user should keep in mind that different Data Files may have
the same name.
