Systematic and separable codes are widely used for error detection in VLSI circuits. Recently systematic codes have been found for detecting r-unidirectional and burst unidirectional errors [I]-. In such codes r checkbits are added to k information bits to form a codeword of length (k + r) , and it is assumed that all 2A possible information k-tuples are present. However, in many applications all 2k possible k-tuples are not used. In such cases we can obtain codes usually referred to as separable codes. We present separable codes which can detect r or all unidirectional errors.
