KiCad

Bonjour,
Comment fonctionne ce logiciel , entre autre la fonction Simulateur
Cdl

Bonjour,

Je ne connais pas le simulateur Kicad mais je vous suggère plutôt d’utiliser LTspice qui est gratuit, puissant et qui bénéficie d’un grande communauté d’utilisateurs.

http://www.analog.com/en/design-center/design-tools-and-calculators/ltspice-simulator.html

Attention, ce logiciel est uniquement en anglais et ne se laisse pas apprivoiser facilement (comme beaucoup de logiciels de simulation ou de CAO d’ailleurs).

Si votre PC est sous XP, il y a un lien spécifique sur la page de téléchargement ci-dessus.

Bonjour
Merci d’avoir répondue rapidement … J’ai toujours un doublons qui s’affiche quand je crée un nouveaux message!! Une idée sur les doublons …

Bonjour,

Oui:

  • C’est parce-que tu cliques deux fois sur envoyer. Il ne faut cliquer qu’une fois.
  • Il est toujours possible et souhaitable d’effacer le doublon avant que quelqu’un y réponde. Une petite croix à coté de « éditer » sert à cela.

bonjour
tu trouveras la reponse ici. tout y est expliqué

Manifestement, Kicad ne contient pas de simulateur.

Bonjour
KiCad eda 2018, contient bien un simulateur

Bonjour,

Si vous le dites…

Le simulateur n’est pas natif avec Kicad. Il faut lui greffer ngspice.

A moins que vous ne prouviez le contraire

Bonjour …

Sur le site de Kikad : http://kicad-pcb.org/download/
il n’est nulle part fait mention d’une version « KIKAD EDA 2018 »
Actuellement, la version téléchargeable est la version 5.0.0
et la version en cours de développement est la 6.0.

Par ailleurs, il n’est nulle part fait mention non pus d’un simulateur
dans Kikad et je n’ai même pas vu la possibilité de lui adjoindre
ngspice. Mais je n’ai pas non plus lu toute la doc avec attention.

Si Lucien68 a plus d’info concernant ses assertions ??

Amitiés
Serge

C’est exactement ce que j’ai dit, aucun simulateur n’est intégré à Kicad.
Il faut lui adjoindre un moteur spice.
Comme ici : https://mithatkonar.com/wiki/doku.php/kicad/kicad_spice_quick_guide

Et ça n’a pas l’air simple…

Yop,yop …

Je n’avais aucune intention de contradiction. C’était juste pour appuyer et documenter le propos. :slight_smile:

Amitiés
Serge

Je sais, Serge, ça ne s’adressait pas à toi… :wink:

la version 5.0.0 de kicad eda est dispo depuis juillet.

Ability to pan using a drag of the right mouse button

Support for loading gerber X2 extensions

Support for loading gerber job files

Packaging Changes

In regard to packaging the KiCad binaries, not a lot has changed. You should mostly be able to bump the package version, but some new major dependencies have been added with the SPICE simulation and support for IGES and STEP 3D models. We now depend on Open Cascade (by default OCE, but OCCT should also work.) We also now depend upon ngspice built as a library.

Beyond dependencies, the library has had a major restructuring such that the footprints are in one git repository and the templates have been separated out to its own repo as well. See kicad-pcb.org/download/source/ for all relevant information.

We hope you enjoy version 5 of KiCad.

CQFD… :laughing:
