I am the KiCad lead developer but the final decision for adding a
feature of this magnitude would require buy in from the lead development
team. If you interested in contributing to KiCad, we can discuss how to
move forward. I suspect that integrating chip design features into
KiCad will be far more difficult than exporting edif files. The
schematic and symbol editors would need to be modified to handle
assigning fab geometry to symbols and passing that information to the
board editor. The board and footprint editors will have to be modified
to support placing and editing the fab geometry. It may be possible to
do this with footprints but I'm not sure editing footprints will work
well with fab geometry. Any simulation outside of ngspice will also
need to be supported. My guess is that the edif export will be the easy
part. All this being said, I for one support the idea of integrating IC
fabrication into KiCad. We just need to do some planning in order to do
ensure this goes as smoothly as possible.
Cheers,
Wayne

Who are the lead developers of KiCAD who take that decision? I think already
KiCAD might be able to do this thing. The only thing not implemented is that of
exporting an edif file.
Thanking you

Hi Sagar,
There is definitely interest in including chip design capability in KiCad, when
that happens really depends on a lot of factors. I'm not familiar with the
code listed below, but a good start to getting a feature like this into KiCad
would be to ensure all of the code in the list below is packaged for all the
platforms supported by KiCad[1]. Once that hurdle is cleared, we would need to
write a design document about how we would integrate support for chip design
into KiCad. After the lead development team agrees on the design document,
then we could actually start any implementation as manpower becomes available.
Cheers,
Wayne

Respected devs,
I was exploring into chip designs and except the aspects of automation of
placement and routing and testing for logic, at the end, semiconductor chip
design is extremely similar to designing a board.
It consists of a bunch of blocks for different Si layers, oxide layers, metal
layers, etc. which in my view is already supported in kicad. If the grid size
is set to be of order of lambda, a parameter in chip design, say like 40nm, an
output of oasis file/edif file can result in a complete EDA.
I welcome your thoughts on this.
Thanking you
Sagar Acharya
