[kicad-users] Netlist Plugin and Hierarchical Nets
Hello, I'm using Kicad (eeschema) to draw schematics for the panel layout of an electrical installation I'm making (specifically, a CNC machine). I have two sheets: an overview sheet (showing the machine's motors, sensors, etc) and a hierarchical child sheet showing the layout for the electrical panel. I need a way to convert the net names into reference numbers, so that I can make all the physical wiring and label each wire with a number, for reference (so I know, for instance, that wire 1 is motor A+ phase, wire 2 is motor A- phase, etc). I figured I'd export the netlist from my project and write a netlist plugin that would process the names of the nets and write a corrosponding table with a wire number (I have to do this because the identifying net numbers are volatile and may change if I change the schematic - I would solve this by having an external database which never modifies the wire number, even if the net is removed from the schematic). However, even the net addresses' in the hierarchy and it's connections to components change when I reprocess the schematic. And this is done in an undeterministic way. An example (slashes denote the position in the hierarchy): I have the components /motorX and /panel/driverX. Both have pins named "A+", "A-", "B+", "B-". I have created the nets "X A+", "X A-", "X B+", "X B-" and connected them to the motor and driver components (each at a separate hierarchical level, therefore they should actually be 8 different nets - "/X A+" and "/panel/X A+"l, right?). However, when I generate the netlist, the temporary netlist file has a mix of the nets (some appear from the root sheet, some appear from the child sheet). I'm using hierarchical labels to pass the signals between the parent and child sheets. Bottom line: it seems that when exporting a netlist, eeschema treats all nets as global, so the first it finds with a name (like "X A+") sets the address (of the net) to the correct value at the moment, but when processing hierarchical sheets that process breaks. I can provide the projects I'm working on and the custom libraries I built. Thanks. -- Matheus Degiovani Gigatron Software e Treinamentos Ltda.

[kicad-users] Netlist Format
Hi Everyone, I'd like to first thank the KiCad contributors for such a well made product. I hope to see it evolve into a great open source option for electronics enthusiasts. Now to my question- I'm currently using Gerbtool by WISE. I've been reading up on netlist verification. From what I gather, when a schematic is created, there is a netlist which is generated (I've done this in KiCad-EESchema). Gerbtool (which I'm evaluating) supports a few different netlist import options. The option I'm using is IPC-D-356. Is this the format of the netlist which EEScheema generates? If not, does anyone know what the format is? Regards, Chiques
Re: [kicad-users] Netlist and PCBNew
where did you get the lib and module from?
If the lib and modules do not match then all sorts of things can go
wrong.
Using the standard KiCad libs (in the connector library) The netlist
gives:
# EESchema Netlist Version 1.1 created Thu 23 Apr 2009 00:51:19 BST
(
( /49EFAB7E USB_A J1 USB_1
( 1 N-02 )
( 2 N-03 )
( 3 N-03 )
( 4 N-02 )
( 5 N-03 )
( 6 N-02 )
)
( /49EFAD07 USB_B J2 USB_2
( 1 N-01 )
( 2 N-01 )
( 3 N-04 )
( 4 N-04 )
)
)
For USB1 / 2 types.
Quite a bit different from yours. So if you are using the Kicad modules
and your lib then I think will be the problem.
The problem is normally that the pin numbers / identifiers don't match In
the kicad parts they are expecting pins called 1,2,3,4,5,6 etc, in your
lib they are called VBUS, D-, D+ GND. So this is the first area to check
out.

[kicad-users] Netlist and PCBNew
Dear Kicad users,
I have a great issue with PCBNEW
My Netlist seems to be OK.
I have 1 usb connector declared in my Netlist as:
( /49BD6464/49D3D7F2/4973DEB3 con-usb-3-USB-MB-H X1 USB-MB-H {Lib=USB-MB-H}
( VBUS +5USB )
( D- N-64 )
( D+ N-70 )
( GND GND_PC )
)
We can see that the 4 pins are connected.
But in PCBNEW, my USB connector have no connection to other components.
When I zoom on my USB connector, I can see that all the connection are barred
(X).
Please could you explain me where is the issue ?
How can I check (without to take a look on each my component) that this issue
exists on another place of my PCB
Thanks in advance
Christian
[kicad-users] netlist & cooper zone
1.how to view netlist number in eeschema so we can change the track size in spectra auto track? 2.Could the cooper zone be included in the 3D view? thank you for the creator of kiCAD such a great software. idisohard!!
Re: [kicad-users] Netlist from EEschema not working in PCBnew

[kicad-users] Netlist from EEschema not working in PCBnew
The 20080715 version of EEschema for Win32 is generating netlist pads for my C and R components that PCBnew can't handle. The netlist shows pins numbered "A" and "B", but if I look at the other components the pins are numbered "1" and "2" and so forth. Moving the whole thing into PCBnew generates a ratsnest that DOESNT include any of the R or C components. If I turn on warnings the Netlist update complains that it can't find some of the pads "A" and "B" from a couple of the components. What gives?
Re: [kicad-users] Netlist Generation and Custom Power symbols
I have managed to do what you want but it was tricky... I suggest that you go back to the power.lib, export again and change only the drawings, step by step.

[kicad-users] Netlist Generation and Custom Power symbols
Hello, I cannot get the netlist generator or ERC check to accept a custom GND or +x.xV power symbol. I want to have a custom GND symbol, and I removed the GND symbol from power.lib. I moved it to my own lib and changed the way it looks only. After this, the ERC and Netlist generation no longer accepts this as a power net indicator, the net it is connected to simply gets enumerated, but never connected to e.g. the GND net. Reverting back to the Kicad original GND symbol (renamed to avoid collision), works as expected. Does Kicad only accept power symbols physically located in the power.lib library? Any ideas anyone? /S

Hi, Im trying to generate a netlist, but I getting this mesage: Item not annotated: 120K Somebody help me
[kicad-users] Netlist format for using Orcad as schematic capture, PCBNEW as layout
Under the "other" tab in the netlist generator is the PCBII netlist format... It works without any alteration and has the advantage of providing footprint names to PCBNEW. Cheers!
