Process gates are for when you know you aren't going to get many iterations. Some things really are one shot or few shot. Example: a set of masks for a silicon chip costs millions of dollars, get it wrong and that's a million dollar coaster. Recognise when you have that problem and when you don't.
- drewcoo 4y agoProcess gates are part of repeated process. Otherwise we'd call them "special one-time checks that we absolutely won't make part of our process." One-shot checks are a thing and have a place, but that's not what the article is about.
- ajb 4y agoWhat I mean by one shot is one shot in that product. You only tape a given chip once (unless you screwed up and somehow still have the money for a redo), but you absolutely expect that you are going to tape out more than one chip if you are a chip company. So it is genuinely part of a process.
