You can find some python scripts to transfer symbols and schematics from LTspice to Kicad.
The goal under that script is to design and simulate under LTspice and to automatically transfer the circuit (or only a part of it) to Kicad to draw the PCB.
For that, you need to have Python installed and in your path under windows only because LTspice is only under Windows. Note that I use and tested the script with Python 3.6 , LTspiceXVII and Kicad 4.0.7 (for other versions, some minor script(s) changes may be needed)
The method is based on those 2 steps in the directory that contains the LTspice symbols (.asy) and schematic (.asc) : in a command window :
run : LTspice2Kicad.bat run : python sch_Ltspice2Kicad.py your_schematic.asc
The first step 1. is based on the python script lib_LTspice2Kicad.py and creates many libraries based LTspice symbols library, and also creates a library with all the symbols of the current directory.
The second step 2. transfers the schematic from LTspice to Kicad and creates 2 files : your_schematic.pro and your_schematic.sch
The current limitations, and so, the to-do list is :
- the hierarchical schematics are not transferred, so only single sheet schematic are properly converted
- the position of the name and value of the component is arbitrary fixed and do not follow the position of LTspice
- the schematics and symbols saved in UTF-16-LE format cannot be converted without script customization, except ADA4807 and ADA4895 symbols
I hope that eeSchema will soon allows python scripts as Pcbnew does to include such a script in my menus.
If you have any remarks or if you have found a bug, I can try some correction.
