Abstract :
In this paper, Self Checking Circuits (SCCs) with sequential functional blocks are studied from the point of view of problems possibly arising at the system level because of internal resistive bridging faults (BFs). Electrical level design rules and checking schemes reducing the occurrence probability of such problems are proposed and their effectiveness is verified. Moreover, the sequential functional blocks obtained with the methodology of this paper are Strongly Fault Secure (SFS) with respect to stuck-at faults
