High speed and highly testable parallel two-rail code checker
In this article we propose a high speed and highly testable parallel two-rail code checker, which features a compact structure and is Totally-Self-Checking or Strongly Code-Disjoint with respect to a wide set of realistic faults. The proposed checker is also particularly suitable to implement embedded two-rail code checkers, as it requires only two input codewords for fault detection. Our checker can be employed to check the correct operation of a connected functional block using the two-rail code, to implement the output two-rail code checker of "normal" checkers for un-ordered codes, or to join together the error messages produced by various checkers (possibly using different codes) present within the same self-checking system. The behavior of our checker has been verified by means of electrical level simulations (performed using HSPICE), considering both nominal values and statistical variations of electrical parameters.

Abstract

In this article we propose a high speed and highly testable parallel two-rail code checker, which features a compact structure and is Totally-Self-Checking or Strongly Code-Disjoint with respect to a wide set of realistic faults. The proposed checker is also particularly suitable to implement embedded two-rail code checkers, as it requires only two input codewords for fault detection. Our checker can be employed to check the correct operation of a connected functional block using the two-rail code, to implement the output two-rail code checker of "normal" checkers for un-ordered codes, or to join together the error messages produced by various checkers (possibly using different codes) present within the same self-checking system. The behavior of our checker has been verified by means of electrical level simulations (performed using HSPICE), considering both nominal values and statistical variations of electrical parameters.
