US Patent:

54327938, Jul 11, 1995

Filed:

Nov 17, 1993

Appl. No.:

8/153194

Inventors:

James P. Comerford - Manhasset NY
Thomas M. Mannle - Franklin Square NY

Assignee:

Grumman Aerospace Corporation - Bethpage NY

International Classification:

H04J 302

US Classification:

370112

Abstract:

A response expander circuit provides to a unit under test a number of response channels which is greater than the number of response channels provided by a basic test control unit. The increased response channel count is accomplished by separating the channels available to the unit under test into two separate patterns, and time division multiplexing the two patterns so that the two patterns are sequentially supplied to the basic test control unit for processing.

International Classification:

G06F 1520

US Classification:

371 27

Abstract:

A low cost, office environment platform for performing off-station verification and integration of Automatic Test Program Generation test program sets for digital circuit boards includes a general purpose computer which oversees integration of the test program sets developed on the simulator with the digital circuit boards using a basic test control unit such as the HP16500 Logic Analysis System. A method of utilizing this apparatus involves generating and simulating the test program sets and applying the test program sets to the digital circuit boards during development with feedback to the host computer on which the test program sets are generated.
