EDIT: after updating yosys to the latest (instead of the ~year-old version below), nextpnr no longer hangs while running placement.

nextpnr-ice40 observed to hang with heap placer when running for https://github.com/andars/spoke at commit 0a4ce72.
(probably the verilog design is invalid somehow, but I haven't figured out how)

    Quotes from The Character of Physical Law, by Richard Feynman


The next question was - what makes planets go around the sun? At the time of Kepler some people answered this problem
by saying that there were angels behind them beating their wings and pushing the planets around an orbit. As you will see,
the answer is not very far from the truth. The only difference is that the angels sit in a different direction and push
their wings inwards. (page 18)


Today our theories of phyics, the laws of physics, are a multitude of different parts and pieces that do not fit together
