+\frame{\frametitle{What is the Libre-SOC Project}
+
+ \begin{itemize}
+   \item An entirely Libre Vector-enhanced Power ISA compliant
+         CPU with enough legs to tackle Supercomputing-class
+         workloads.
+        \vspace{6pt}
+   \item Working closely with the OpenPOWER Foundation: no
+         rogue custom instructions.  Both Long-term stability and
+         open-ness is key.
+        \vspace{6pt}
+   \item Huge reliance on Python OO and Software Engineering as
+         applied to HDL. Not just traditional Verification: unit
+         tests at every level, Formal Correctness Proofs as unit
+         tests. "python3 setup.py test"
+        \vspace{6pt}
+   \item Using Libre VLSI Tools: coriolis2 (by Sorbonne University)
+         ultimate goal is to have the GDS-II Files publicly reproducible
+        \vspace{6pt}
+
+  \end{itemize}

+
+
+\frame{\frametitle{What challenges does a Crypto-Wallet ASIC face?}
+
+ \begin{itemize}
+   \item Industry-endemic paranoid 5-level-deep NDA Chain.  Foundry NDAs
+         themselves are under NDA. Sharing between teams inside the same
+         company is prohibited! Cell Libraries: NDA'd. PDKs: NDA'd.
+         HDL designs: NDA'd.
+        \vspace{6pt}
+   \item Power-analysis attacks. Timing attacks. EMF attacks.  Standards
+         Verification (FIPS ain't it).  Toolchain attacks.  Cacheing is out:
+         performance will suck.
+        \vspace{6pt}
+   \item Achieving Full Transparency - a critical goal - is almost impossible
+         to achieve.  Ultimately, you need to buy (or build) your own Foundry.
+        \vspace{6pt}
+   \item Production and Development costs (NREs) almost certainly dwarf the
+         Sales costs.
+        \vspace{6pt}
+  \end{itemize}
+}
+
+
+\frame{\frametitle{Pragmatic solutions}
+
+ \begin{itemize}
+   \item Use Formal Correctness Proofs at every step. Caveat: proofs are
+         only as good as the mathematicians that write them!
+        \vspace{1pt}
+   \item Work with Standards bodies (e.g. OpenPOWER Foundation ISA WG) and
+         Members with similar interests.
+         Custom Extension with zero public review == bad.
+        \vspace{1pt}
+   \item Unstable PLLs to detect rogue EMF
+        \vspace{1pt}
+   \item Develop a product that has a larger total market (an SoC)
+        \vspace{1pt}
+   \item Accept that some levels of NDA are "out of reach" for now.
+        \vspace{1pt}
+   \item Use E-Fabless "ChipIgnite" to at least get the NREs down.
+        \vspace{1pt}
+   \item Ultimately: buy your own Foundry, make the PDK and Cell Library public.
+         Only use Libre VLSI tools (limits to around 130 nm at the moment).
+         Everything is "early days" in this space
+        \vspace{1pt}
