  • Patent number: 5144229
    Abstract: A method for automatically generating an in-circuit board test for a circuit board, comprising a plurality of Interconnected digital devices, selectively provides conditioning only to devices which need conditioning. Devices which need conditioning include outputs which should be conditioned prior to being back-driven and problem devices (such as oscillators) which interfere with the testing of other devices. The device outputs which require conditioning are flagged in a device models library which contains predetermined generic test models for the devices on the board.
