  • Testing macros embedded in LSI chips
    Patent number: 4225957
    Abstract: Testing combinatorial logic sectioned into macros. The macros perform functions some of which are linear, such as busses, and some of which are non-linear such as PLAs, with the macros being connected so that the total chip can be tested by testing each macro individually to thereby make it unnecessary to model the totality of the macros collectively in terms of primitive logic.
