Last year's conference was a smaller event (one day only) and the slides are available here:

We contacted foundries too - let's see how far we can go in the direction of opening the PDKs: We have already fabricated RISCV chips, but various NDAs did not allow to publish layouts. We are working to change that. At FSiC there will be a session about this too.
