RAM Manufacturing testability (MBIST) #159

Open Blebowski opened 1 year ago

Blebowski commented 1 year ago

Hello,

within a company for which I do digital design, we are using 55 nm technology (proprietary) with proprietary memory compiler. As we are moving closer to serial manufacturing, we are starting to deal with memory testability of all macros. Basically, we are wondering whether we should insert an MBIST core by a commercial tool, or whether we should design our own MBIST core (for March X, C patterns).

As OpenRAM is a memory compiler itself, we were wondering whether there is some fuzz in the OS about memory manufacturing testing (some MBIST cores or solutions available).

We are thinking about open-sourcing this IP core once designed, and also big portion of our RTL design.

Btw. our web-page: Tropic Square

We are working on BIST but it isn't ready at this time. I'm not sure I have a timeline that I could commit to.

Thank you for answer, please keep us posted when you have something. We will do the same, since we intend to open-source significant portion of our design.
