1.所有的MBIST设计应该考虑diagnose,加入diagnose电路,方便诊断mem故障,这会在芯片量产时大大提高成品率。 2.由于ARM与Mentor有合作,Coretex-A9以上的ARM核具有share-bus接口,可以很好支持Tessent Mbist,就能够实现ARM内核的mem的高速测试和访问,也提高了ARM CPU的性能。 3.Tessent MBIST会使用JTAG,只占用TCK/TMS/TDO...

Try not to use the programmable pull-ups which are provided in the I/O pads of some processors and FPGAs to enable external logic to operate. If the pull-ups required on an IIC bus were only provided by programmable pull-ups then any devices attached to the IIC bus may not be testable...
