10th Asian Test Symposium (ATS'01) A Unified Scheme for Designing Testable State Machines Kyoto, Japan November 19-November 21 ISBN: 0-7695-1378-6
An approach for designing state machines that have built-in on-line and off-line testability is proposed. The next state logic is designed using transmission gates and tri-state buffers only. The resulting machines have scan_in/scan_out capability that allows off-line testing of the next state logic. The on-line testing capability for erroneous state transitions is achieved by EX-ORing the outputs of two registers that store the current and the next state of a machine, and checking for even parity at the outputs of the EX-OR gates.
