Hi there,

I have been exploring gerber and IPC-2581, I have some prototype code
written in Qt/C++, see
https://gitlab.com/chgans/le-ipc2581-viewer

Most of the code is generated, i've rewritten their XML schema into a
mard-down like syntax, which is them parsed by a python script to
generate all the data structure and the XML parsing, the rest of the
code is just visualisation

The standard is sort of open, I was able to write this viewer based on
publicly available document and sample files, see:
- https://gitlab.com/chgans/le-ipc2581-viewer/tree/master/docs
- https://gitlab.com/chgans/le-ipc2581-viewer/tree/master/testcases.

It might take a while for this standard to be adopted, but you have to
realise that this standard offer way more than gerber, it's been
designed for improving the whole design to manufacturing chain.
Just an example, it has built-in support for stack-up specifications,
covering both physical and electrical constraints, ...

Major EDA vendors have support for exporting in this format (according
to IPC website).
Some stack-up specialised (proprietary) software support this format
as an input and output.

It should not be difficult to create an exporter for KiCAD, reading,
interpreting and rendering this files is another story.

I personally use QtCreator on Linux/OSX/Windows, for hacking C++ project.
See http://doc.qt.io/qtcreator/index.html

Qucs is way more than (ng)spice, integrating the qucsator simulator
engine would benefits KiCAD.
This would allow to simulate PCB layout and open the door to
parameterised layout. AFAIK, one of the main Qucs focus is RF
simulation.

A tighter KiCAD/Qucs/GnuCAP would be highly beneficial to the community.

Maybe you're planning to talk about that at FOSDEM .

My 2 cents,
Chris

CC qucs-devel, but I doubt the cross-posting will work for everyone.
