Qucs GSOC 2015 Ideas

Here is the list of our ideas for GSOC-2015. These ideas were contributed by our developers. You can implement each of these ideas or propose your own. For more details contact with person responsible for this idea.
Brief explanation: Currently we have two passive filter synthesis systems:
qucs-filter and unfinished qucs-filter-v2. We want to merge them into one.
It's need to backport some features from qucs-filter-v2 to
qucs-filter(Legendre and Blinchikoff filter transfer function
approximations). See https://github.com/Qucs/qucs/issues/161 . Also we want to
add Legenedre approximation to qucs-activefiler (active filters synthesis
tool). It's desirable to add inductor coupled resonators topology (see
schematic) for passive filters. This topology is important for high-power
output fiters of RF power amplifiers.
Expected results : New transfer function approximations and filter
topologies in qucs-filter
Task level : easy
Required skills : C++, Qt, mathematics, electronics or electrical engineering

Brief explanation : Qucs has not so may components in its system library. Especially it concerns Inegrated Circuits (ICs) such as opamps, switching circuits, power supply circuits, optocouplers. Transistors (bipolar and FET) are also desired.
It is need to add as many as possible components in Qucs library. Components models should be converted from SPICE models that are provided in datasheets. Perhaps it's need to implement scripts for auto conversion of these models. Especially it concerns opamps.
Expected results : More components in Qucs library
Task level : easy
Required skills : XML, scripting languages (Bash, Python, etc.), SPICE models, electronics or electrical engineering

Brief explanation : Qucs libraries have XML text format. There is no GUI library editor now. It requires open library with text editor and edit it manually. You will need to implement Qt-based GUI qucs-tool "Library editor".
Expected results :
Lirary editor should perform the following functions:
- Edit component name and description
- Attach component models from Qucs netlist or schematic
- Attach Verilog and VHDL models
- Attach component symbol
- Attach specific netlist node names to component symbol pins
- Edit component model or netlist
- Convert spice model to Qucs model
Task level : medium
Required skills : C++, Qt, SPICE models, electronics or electrical engineering
