Do MBIST and normal function use the same data path?

Post by iSTART »

[Question] After inserting iSTART MBIST into IC, whether MBIST and normal function use the same data path?

[Answer] If memory without test port, after inserting MBIST into memory, it will add one more MUX in front of memory. This MUX can switch the data path between MBIST or normal function. So, while executing MBIST testing, MUX will switch to MBIST data path.
