step by step to implement BIST

[soloktanjung]

hi,

i'm a little bit confuse on how to implement BIST in the design? from what i have read, i think that we insert BIST in the RT level. anyone can help?

thanks in advance.

i know memory BIST can be accomplished using eda tools.

so means that i've to find the tools for my project.

thanks.

BIST: Built-in self test
Put the test circuit (test sequence control + pattern generator + result comparator)
into the design.

Yes. There are some tools support BIST insertion.

OR
You can wirte the RTL code of pattern generator according to the specific BIST algorithm.
Tool just simplify the process and generate those RTL codes for you.

You can use tool, or you can write it yourself.
