As this was not posted yet officially, I guess you can't share it because of NDA. Can you at least post the footprint used from both 16nm and 250nm chips and on which pin is the CLK for 16nm - that would be enough for me re 16nm.
For the 250nm one ... I think it is not the same chip as on StringPowerBlock.pdf, but the same one as on 1block_short.jpg ... can you confirm please?
