Yeah, this is good article. Maybe recently many design articles pushed this quickly off the top view. First time I saw it, thanks to your post.

Good article, I am surprised no one commented (though I am late on this by several weeks!). The figures are unreadable, like figure 2, where I would like to learn more about the cost model used. The authors make a number of observations based on their cost model, some of which I find hard to agree with. These costs are very product-dependent and it is conveivable to have many dice for example in a 5-dice stack where the middle ones may need minimal test. The authors also gloss over details on how to probe TSV's & microbumps which are custom to each application/product. Some of the failure modes described in figure 1 can not be determined by the contemporary probing technologies. MP Divakar

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
