Hi all iam working on the cygnal microcontrollers c8051f124, actually i have to perform self check of microcontroller on power on i have written some routines for RAM and how self check the cpu of microcontrollers ie i have to check the registers and cip 51 if any one having ideas please reply REGARDS nEiL
The question here is detecting more subtle errors in cores embedded into other products, that might have a small defect in just one part of the CPU core. Embedded self-testing can save the addition of lots of extra test logic on the chip, or, if you have a fast processor, even save time compared to external test devices. I see, but that is hardly self-test since it requires an testbench setup. I believe(d) - maybe the original poster will enlighten us - that the question referred to production units. Erik
