MBIST and LBIST demonstrator

To demonstrate fully the applicability of the BIST schemes for both memory and logic functions the design of a commercially available 8-bit microcontroller incorporating these test strategies was undertaken. This circuit was also chosen as CISSOID had designed a version of this microcontroller. In the demonstration vehicle the 8-bit microcontroller was combined with 32K x 8bit memory block. The overheads incurred by the test scheme amounted to a few percent.

The results from the incorporation of both logic and memory BIST into a single chip 8-bit microcontroller with integrated memory (8 x 32K) would be of interest to semiconductor manufacturers, IC design houses, SoC and SIP designers, also to users of microcontrollers.
