Re: who has some suggestions on DFT of multi_core processo
I will do some DFT of multi_core in several months, so now I only want to find some examples to increase my confidences about that.
I want to ask a question: if there r 16cores in a processor chip, and they are the same with each other. And the pin's numbers of the chip is almost equal to the single core chip. Thus,
(1) for every core's MBIST, control singals: how to translate them?
(2) In order to reduce the test time, I hope the 16 cores are best to test simultaneously, but how to input the patterns and output the responses?
(3) what's more, if we will use the 65ns technics, what types of test should I pay more attentions to? at-speed, delay path? is the IDDQ test useful as well?
so, I feel very confused about the project so far. any suggestion of yours will give me some confidences. thanks a lot!!
