PET PDK was supposed to be done by the end of 2014.
POET PDK, presumably, was to be completed some time later.
and then this...
PET Foundation Process Design Kit ("PDK") targeting 40-nm - Sentaurus modeling (a Synopsys tool) has been performed with new fabrication innovations to achieve controlled scaled device operation. These modeling predictions are guiding and confirming the device prototype development and testing. The PDK milestone has been moved to Q1 2015 so that the release incorporates the latest innovations currently being developed in the UCONN Lab and in parallel with the "3rd party foundry".
So delayed until Q1 2015 for the PET PDK...
Then AC died, they formed a partnership with BAe, formed the TRAB, hired Todd, David, Subhash and Suresh....and everything changed.
The PDK's have not been mentioned since to my knowledge..
