LTspice is one of the best schematic entry tools out there. It lets you draw any schematic imaginable. LTspice's simple appearance belies its true power.
-
You can draw graphs for computer science.
-
You can define buses.
-
You can nest schematics for complex hierarchies.
Now if only we could use these schematics in a Python GUI.
The AscCanvas class lets you import a schematic and show it as a wxPython window. It supports zooming, scrolling, searching and subclassing. It uses rtreelib to look up symbols and nets under the mouse pointer.
To show a schematic, you will need to import these files:
-
ASY files are symbols, i.e., components, and they are imported in batch by specifying a list of paths. Load them by calling
AscCanvas.load_symbols() -
ASC files are schematics. They define the connectivity between instances of symbols. Load them by calling
AscCanvas.load_asc().
asc_viewer is a demo executable that lets you open schematics and shows how to use AscCanvas.
pip install asc_viewer
