Abstract :
Single BJT BiCMOS devices exhibit sequential behavior under transistor stuck-OPEN (s-OPEN) faults. In addition to the sequential behavior, delay faults are also present. Detection of s-OPEN faults exhibiting sequential behavior needs two-pattern or multipattern sequences, and delay faults are all the more difficult to detect. A new design for testability scheme is presented that uses only two extra transistors to improve the circuit testability regardless of timing skews/delays, glitches, or charge sharing among internal nodes. With this design, only a single vector is required to test for a fault instead of the two-pattern or multipattern sequences. The testable design scheme presented also avoids the requirement of generating tests for delay faults
