Timing Error Detection and Correction by Time Dilation
Résumé
Timing failures in high complexity - high frequency
integrated circuits, which are mainly caused by test escapes and
environmental as well as operating conditions, are a real concern in
nanometer technologies. The Time Dilation design technique supports both
on-line (concurrent) error detection/correction and off-line scan
testing. It is based on a new scan Flip-Flop and provides multiple error
detection and correction at the minimum penalty of one clock cycle delay
at the normal circuit operation for each error correction. No extra
memory elements are required, like in earlier design approaches in the
open literature, reducing drastically the silicon area overhead, while
the performance degradation is negligible since no extra circuitry is
inserted in the critical paths of a design.
