Abstract:
1. A method of operating an automatic test system programmed with a test pattern comprising a plurality of vectors, the plurality of vectors each being associated with a location within the test pattern, and each of at least a portion of the plurality of vectors comprising an operation portion and a data portion, the operation portion defining an operation to determine a location of a subsequent vector during execution of the test pattern, and the data portion at least in part characterizing actions to be performed by the test system to generate or measure test signals at a plurality of test points of a device under test upon execution of the vector, the method comprising: executing vectors in the test pattern with circuitry comprising a plurality of paths, each of the plurality of paths configured for processing operation portions of vectors and each of the plurality of paths pipelined with a plurality of ranks, the executing comprising:
