Abstract

Embodiments relate to matrix and compression-based error detection. An aspect includes summing, by each of a first plurality of summing modules of a first compressor, a respective row of a matrix, the matrix comprising a plurality of rows and a plurality of columns of output bits of a circuit under test wherein each output bit of the circuit under test comprises an element of the matrix, and is a member of a row of a column that is orthogonal to the row. Another aspect includes summing, by each of a second plurality of summing modules of a second compressor, a respective column of output bits of the matrix. Yet another aspect includes determining a presence of an error in the circuit under test based at least one of an output of the first compressor and an output of the second compressor.
