Im trying to learn a bit about the techniques to create an ASIC. I found that the NRE-Costs are the biggest cost part which means the creationg of the masks and you get a minimum number of ASICs back.
Shuttle Services seems to be cheaper which means that more ASIC-Designs are done at the same time. So the part of the costs one has to pay is smaller. But the resulting ASICs are less too.
But what about the masks resulting from that. Are they have a disadvantage against a dedicated run? I mean will producing more ASICs be more expensive since the mask only is for, maybe, 1 ASIC instead a full mask for many of the same ASICs?
In fact my question is if the costs one is saving by using shuttle services is firing back later when producing more ASICs.
If someone knows... whats the cheapest way to get a most optimized (custom) ASIC that has the potential to create more of the same ASICs for cheap later. Maybe 28nm or even lower...
