ABSTRACT:
Methods and apparatus are provided to insert errors into digital data. The errors can be inserted into the data itself, or into the corresponding error correcting code bits. The invention comprises a register, whose contents are combined with data using exclusive-OR circuitry. By varying the contents of that register, an error can be inserted into a specific bit in a particular data word, or into multiple bits in the same word.
