libmodbus is a library to send/receive data with a device which respects the Modbus protocol. This library can use a serial port or an Ethernet connection.

This package provides a full Python driver for the Keithley 2600B series of source measurement units. This driver provides access to base commands and higher level functions such as IV measurements, transfer and output curves, etc. Base commands replicate the functionality and syntax from the Keithley's internal TSP Lua functions.

LibSavitar is a C++ implementation of 3mf loading with SIP python bindings. It belongs to the Cura project from Ultimaker.

ADMS is a code generator that converts electrical compact device models specified in high-level description language into ready-to-compile C code for the API of spice simulators. Based on transformations specified in XML language, ADMS transforms Verilog-AMS code into other target languages.

Manifold is a geometry library dedicated to creating and operating on manifold triangle meshes. A manifold mesh is a mesh that represents a solid object, and so is very important in manufacturing, CAD, structural analysis, etc.. Manifold also supports arbitrary vertex properties and enables mapping of materials for rendering use-cases.

Gaf stands for “gschem and friends”. It is a subset of the entire tool suite grouped together under the gEDA name. gEDA/gaf is a collection of tools which currently includes: gschem, a schematic capture program; gnetlist, a netlist generation program; gsymcheck, a syntax checker for schematic symbols; gattrib, a spreadsheet programme that manipulates the properties of symbols of a schematic; libgeda, libraries for gschem gnetlist and gsymcheck; gsch2pcb, a tool to forward annotation from your schematic to layout using PCB; some minor utilities.
