LTspice to Kicad schematic conversion

ltspice2kicad's Issues

sch_LTspice2Kicad.py - "ValueError: max() arg is an empty sequence" with LTSpice ver. Jan 11 2019

Script execution stopped in sch_LTspice2Kicad.py he line after the coment:

Calcul of min and max of X and Y to choose the page size : A4, A3, A2 A1 or A0

with error

ValueError: max() arg is an empty sequence

because theres no RECTANGLE in my file.asc.

Dirty solved: Commented out every "..rectangle.." array.

X_max = max(max(sym_X),max(wireX1),max(wireX2),max(text_X)) #,max(rectangleX1),max(rectangleX2)

After that, i can use the script and after a few errors while loading it to KiCAD 5.0.2, i got the schematik.
Thank you for your work!

Thats my file.asc for debugging, if you like to.

Contribution to Open Source Tools

Dear Laurent,

I am from eSim Team of FOSSEE, IIT Bombay. We work in promoting the eSim Open Source Tools. Here is our website:

1. https://esim.fossee.in/home
2. https://fossee.in/

We were quite inspired by your LTSpice to KiCAD Converter. Even we have a similar converter for PSpice. Would you like to work with us?

Please share your contact details with us at the following email address:

Thank You.

Utilisation de votre convertisseur de bibliothèques

Bonjour,
je réalise actuellement une interface KiCad vers LTspice pour que la saisie de schéma se fasse totalement sous KiCad et la simulation sous LTspice. Mon interface permet de configurer la simulation .ac, .tran, ..., Monte Carlo, Worst Case ...
J'ai réalisé un convertisseur pour les composants standards (.ind, .cap, .bead) et comme j'ai vu votre convertisseur (que j'ai modifié pour "détecter" les fichiers utf-16le et le rendre compatible avec KiCad 5), je souhaiterai intégrer cette version modifiée à mon dépôt à venir.
M'y autorisez-vous ?
Cordialement,
Eric PERONNIN
