This paper contributes to the field of test engineering: it shows the tradeoffs and engineering aspects of a low-cost, flexible SRAM MBIST engine, applied to the 768 and 256 byte SRAMs of an 8051 microcontroller. The simplicity and orthogonality of the architecture allowed for a full-custom implementation by Micronas in 120 hours of design time, while the area is reduced by 75% of an earlier commercial version.
