Optimal Configurations of Cell Automata to Generate Test Stimuli for VLSI
"... Abstract It is impossible to test a VLSI chip for malfunction by exhaustively checking all the states that the chip can assume. So a chip is usually checked by some mechanism of random sampling.

Abstract It is impossible to test a VLSI chip for malfunction by exhaustively checking all the states that the chip can assume. So a chip is usually checked by some mechanism of random sampling. In this paper, we are concerned with the use of linear CA, i.e. hybrids of rules 90 and 150 CA, for generating random test patterns to test VLSI chips. If the number of cells of 90/150 CA is n, the maximum possible period of the output sequence of any cell is 2n1. It is also known that the output sequence of any cell of a maximumperiod CA is the same as the output sequence of another cell of the same CA except the phase shift. Since the output sequences of all the cells are used in parallel as random test patterns, it is important that the phase shift between any pair of output sequences is sufficiently large. This paper reports the computational results of the search for such CA’s as well as the cross correlations of any pair of output sequences. 1
