    摘要: A method of testing a tristate element by applying a given value to the tristate, applying an opposite value to a keeper element connected at an output of the tristate, capturing a first value at a downstream position of the tristate, evaluating a second value at the output of the tristate using the first value, comparing the second value to the opposite value, and producing a failure code for the tristate when the second value is not equal to the opposite value. Then, applying the opposite value to the tristate, applying the given value to the keeper element, capturing the first value, evaluating the second value using the first value, comparing the second value to the given value, and producing a failure code for the tristate when the second value is not equal to the given value. A passing code for the tristate is produced when a failure code has not been produced.
