Hi i want to know how people are making asics.
I don't want to make my own i know its very expensive i just want to know how are they working.
I'll take a slightly different interpretation of your request, and assume you want to learn about assembling asics into usable devices. There have been some excellent discussions about this here on our own forum,
the NanoFury project is a great resource https://bitcointalk.org/index.php?topic=321287.0;topicseen as a starting point.
Have a look at that, see if it's interesting to you.
Regarding the development of ASICs themselves, you could look into some of Global Foundries generic videos for background info. If you really want see a clear example from the other side of the fence, of ASIC development failure look into Black Arrows incompetent development methods. That was a text-book example in how to underestimate the scale of work involved in developing at ASIC. They have ended up with a working chip, but are facing massive accusations of fraudulent claims, incompetent management, poor service, and basically alienated the entire mining community in the process. It seems like their engineers initially had no clue and failed on various basic electrical engineering challenges, including their own back-planes.
