SKIDL: Use Python to Describe Electrical Connections, Export Netlist for PCB Design

Cool initiative from Dave Vandenbout of XESS Corporation:

SKiDL is a module that allows you to compactly describe the interconnection of electronic circuits and components using Python. The resulting Python program performs electrical rules checking for common mistakes and outputs a netlist that serves as input to a PCB layout tool.

Features

  • Has a powerful, flexible syntax (because it is Python).
  • Permits compact descriptions of electronic circuits (think about not tracing signals through a multi-page schematic).
  • Allows textual descriptions of electronic circuits (think about using diff and git for circuits).
  • Performs electrical rules checking (ERC) for common mistakes (e.g., unconnected device I/O pins).
  • Supports linear / hierarchical / mixed descriptions of electronic designs.
  • Fosters design reuse (think about using PyPi and Github to distribute electronic designs).
  • Makes possible the creation of smart circuit modules whose behavior / structure are changed parametrically (think about filters whose component values are automatically adjusted based on your desired cutoff frequency).
  • Can work with any ECAD tool (only two methods are needed: one for reading the part libraries and another for outputing the correct netlist format).
  • Takes advantage of all the benefits of the Python ecosystem (because it is Python).
