I didn't do any optimizations besides the initial ones Yosys does
automatically. There is probably room for some optimizations, esp in
regards to flattening the design and logic minimization.

It could be interesting to set up a real yosys synthesis script that
alos perform optimiations. I need to get Yosys installed on my compute
machine first though. Since mapping took four hours on the laptop.

Cryptech runs optimization as part of FPGA implementation. Not sure how
well Yosys is able to map modules to tech specific hard macros. Some of
the cores in Cryptech are based on instantiating Xilinx black boxes.
