Abstract

Methods and structure for storing context data regarding electronic test equipment and the device under test or stimulus sources in a manner integrated with the capture and storage of test data as well as test setup data associated with a test environment. The context data may include information regarding parameters of the test environment (e.g., test equipment or test bench set points and configurations, configuration information regarding the device under test, etc.). The context data may be provided in the form of standard textual data as well as user voice sequences to be recorded. The context data is associated with any stored test data or test setup data so as to be easily retrieved along with the retrieval of the associated data. The data are associated by any of several methods including file naming conventions, structured files, table lookups, etc. Use of present invention therefore avoids many problems inherent in prior manual processes in which context data may be lost, incorrectly recalled, or disassociated with the corresponding test data and test setup data.

7. The method of claim 1

wherein the step of associating said context data with said test data includes the step of:

storing said test data in a disk file identified by first file name, wherein said first file name includes a common portion and a unique portion, and

wherein the step of storing said context data includes the step of;

storing said context data in disk file identified by a second file name, wherein said second file name includes a common portion substantially identical to said common portion of said first file name and a unique portion.

8. The method of claim 1

wherein the step of associating said context data with said test setup data includes the step of:

storing said test setup data in a disk file identified by first file name, wherein said first file name includes a common portion and a unique portion, and

wherein the step of storing said context data includes the step of;

storing said context data in disk file identified by a second file name, wherein said second file name includes a common portion substantially identical to said common portion of said first file name and a unique portion.

9. The method of claim 1

wherein the step of associating said context data with said test data includes the step of:

storing said test data in a disk file identified by first file name, wherein said first file name includes a common portion and a unique portion,

wherein the step of associating said context data with said test setup data includes the step of;

storing said test setup data in a disk file identified by second file name, wherein said second file name includes a common portion substantially identical to said common portion of said first file name and a unique portion, and

wherein the step of storing said context data includes the step of;

storing said context data in disk file identified by a third file name, wherein said third file name includes a common portion substantially identical to said common portion of said first file name and a unique portion.

10. The method of claim 1

wherein the step of associating said context data with said test data includes the step of:

storing said test data in a first section of a disk file, and

wherein the step of storing said context data includes the step of;

storing said context data in a second section of said disk file.

11. The method of claim 1

wherein the step of associating said context data with said test setup data includes the step of:

storing said test setup data in a first section of a disk file, and
