Well I am conservative on my personal estimates of how many foundries have operational PDK's. All I know is that if Lightwave has been working with 7 foundries then eventually there is a good possibility that all 7 will have operational PDK's if demand is there.

For now my conservative side believes there are two, one in NA and one in Europe. Could there be more yes. My liberal side says 4. Could there be more. Yes.
But I won't allow myself to post any more that 3 at this point. My personal view and the third is a guess.

As to data sets and release of that data............ My understanding of ALT (accelerated life testing). is that this is a very very comprehensive testing procedure requiring no less that 30 in the sample size and likely no more that 100 samples of operational devices from foundries. In any case a 95% confidence interval is the required goal. It is the only way of capturing the mean value. Otherwise all testing will have zero impact upon the confidence of the clients. The "bathtub" curve that will be completed in this robust data set analysis tells all. I will want to see the white paper from this but doubt I can get my hands on it. But for sure the data will reveal all of what we will need to see.

Best to you,
