The examples in the README are parts from examples/small
. To run the examples do cd examples/small
and run make all
But I agree the documentation isn't very good, it's still all very unstable, and the example doesn't autoroute unless you disable this line because there isn't multilayer support yet and the packing is to dense #7
from pycircuit.
Hmm, looks like the module isn't properly exported.

I am slowly getting there. Just compiling monosat. Will send a pull-request with fixes.
It would be nice to have the examples in the README be runnable in ipython or whatever if this is installed. I think that's what people would expect. Can I change the README?
from pycircuit.
This is what I have in my .zshrc
file:
export PYTHONPATH=$PYTHONPATH:~/repos/pykicad:~/repos/pycircuit2:~/repos/monosat/src/monosat/api/python:~/repos/build/z3/python
Can I change the README?
Yes
from pycircuit.
Ok, I managed to run it fully by installing the monosat python package and copying the compiled libmonosat.so into it ($PYTHONPATH would do it too). Looks like it can't solve the routing though, is that expected?
Solving in Monosat...

Regarding all the packaging trouble I have opened up an issue on monosat which will need to be packaged to handle the dependencies properly.
from pycircuit.
Yes, as I mentioned, to solve the routing multilayer support is required since the packing is too dense.
But I agree the documentation isn't very good, it's still all very unstable, and the example doesn't autoroute unless you disable this line because there isn't multilayer support yet and the packing is to dense #7
from pycircuit.
Also note that it's still very slow, there are some options that can be enabled and the routing time is most affected by the pcb area. I needed a 0.05mm grid for the pads on the QFN package to be represented correctly, if you reduce the grid to 0.15mm spacing it will be a lot faster.
