Since it's obvious I couldn't find my ass with a map in the chip fab world, how about clarifying a couple of things:
"unpackaged" means the bare die with no carrier? right?
"3mm2" is the die size?
What is "... the required CAD/toolchain" to design (tape out?) something like sidehack was proposing?
We, as a company, have a couple of other chip concepts outside the crypto currency world.
If the cost of the S/W isn't to prohibitive and we knew what we were looking for/pricing we might spring for it.
Thanks in advance.
You won't like my answer, but I have to reiterate what I wrote in response to sidehack. You can't afford to ask stupid questions. If you behave like a time-wasting crank, people will treat you like a crank or crackpot. Both MOSIS and Europractice don't have funds to employ salesforce that could tolerate such inquiries. It is presumed that the prospective customer of theirs is sufficiently intellectually inquisitive to read information on their websites.
Europractice serves only European countries plus some culturally related territories, like ex-Euro colonies or ex-USSR. PlanetCrypto is based in US, so you will only qualify for MOSIS. I referred to Europractice partly because of my background and partly because more of the Europractice's site is available for non-members, before signing off the NDA.
