Invariant-based concurrent test schemes can provide economical solutions to the problem of concurrent error detection. An invariant-based concurrent error-detection scheme for linear digital systems is proposed. The cost of concurrent error-detection hardware is appreciably reduced due to utilization of a time-extended invariant, which extends the error-checking computation over time and, thus, reduces hardware requirements. Error-detection capabilities of the scheme proposed in this work are analyzed and conditions on the implementation for achieving complete fault coverage are outlined. Implementations fulfilling such conditions have been shown through experiments to provide 100% concurrent fault detection
