Efficient test generation for built-in self-test boundary-scan template
Prawat Nagvajara, Mark G. Karpovsky, Lev B. Levitin · 2002
An analysis and design of a pseudorandom pattern generator, (PRPG), based on a linear recurrence, for built-in self-test (BIST) boundary scan design is presented. The authors present for the case when r>or=s, a design of an s-stage PRPG capable of producing 2/sup s/-1 distinct r-bit patterns within 2/sup s/-1 clock pulses independent of the hardware realization of the PRPG. For the case when r>
