Setup and running examples

[kasbah]

Hey, I just had my first go at trying to run this. I am assuming it is for python3 as I get SyntaxErrors with python2. So I have done:

virtualenv venv3 -p/usr/bin/python3 && source venv3/bin/activate
pip install . 

When I run the examples from the readme it gives:

Devices

Traceback (most recent call last):
  File "examples/device.py", line 6, in <module>
    Pin('XTAL_XI', Fun('XTAL', 'XI')),
  File "/home/kaspar/projects/pycircuit/venv3/lib/python3.5/site-packages/pycircuit/device.py", line 35, in __init__

    raise IndexError('No Bus with type ' + type)

Assign footprints

Traceback (most recent call last):
  File "assign.py", line 3, in <module>
    circuit = top()
NameError: name 'top' is not defined

And I haven run the remaining ones because they seem to require circuit.

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

[kasbah]

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?

[dvc94ch]

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

[kasbah]

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...
s UNSATISFIABLE
Makefile:11: recipe for target 'route' failed
make[1]: *** [route] Error 1
make[1]: Leaving directory '/home/kaspar/projects/pycircuit/examples/small'
Makefile:18: recipe for target 'all' failed
make: *** [all] Error 2

Regarding all the packaging trouble I have opened up an issue on monosat which will need to be packaged to handle the dependencies properly.

[dvc94ch]

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

[dvc94ch]

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.
