At the moment, I don't have schemantics for regulator and charge pump. Possibly pin configuration for microcontrollers. I'll do this by myself in some amount of time, but if you want to help me, your plannings can reach the silicon. Unfortunately it's quite expensive, but check out for information. Europractice offers MPW runs, too, with much cheaper prices.
First step is to find out possible tools.
ASIC design companies use very expensive designing tools, but I can't afford those. If layout generation is done by hand from logical design, it's very probable that you make an error and you waste your money. This means, that if I use that kind of cell library, I can't share design via Internet. Later chips contains actual processor core with additional units.
