#Port qucs to android code

I agreed that code of spice3f5 dataset to Qucs dataset converted need to be further refactored. What way you suggest? I think the first way is more What documentation did you mean? I didn't write any documentation for spice4qucs branch. Ngspice will use its own equations and qucsactor will use its own equations. It's need to save these equations at specific section of XML schematic document. Spice-specific equations may be defined inside Ngspicesimdialog window.

Do not convert equations on schematic page and ignore it during simulation with ngspice.

It is need to move or clone equation solving engine from qucs-core to qucs-gui and despite this factor there may be spice-incompatible functions. After simulation we can process output data from ngspice or qucsator and resolve equations.

We can move equations evaluation to post-simulation stage.

There may be spice-incompatible mathematical functions. After simulation we will see equatoin variables in ngspice output dataset.

We can try to convert equations to ngspice notation and include them to spice netlist.

There may be three ways to process equation during simulation with ngspice. Yes, I leave ngspice-style traces naming.Īlso we need to process equations on schematic page.

Subcicuits and spice circuits implementation.

You can compare ngspice and qucs simulation results.

You can select and place traces on diagram. Then place diagram and select _ngspice dataset. Spice simulation output is located at $HOME\spice4qucs\ Now spice netlist is at $HOME\spice4qucs\spice4qucs.cir. Perform following actions to perform ngspice simulation: Only AC and Transient simulation are supported. Now you can simulate RCL-circuits from Qucs with ngspice. Now all code responsible for spice netlist creation and ngspice execution is located inside dialogs/ngspicesimdialog.cpp and dialogs/ngspicesimdialog.h See branch spice4qucs at my fork of qucs. The first version of ngspice dataset to qucs dataset conversion is ready for action. Now switch to system terminal and execute ngspice: Spice netlist is located at $HOME/.qucs/spice4qucs.cir. To test spice4qucs open this schematic with Qucs, then execute Simulation->Simulate with spice.

Linear dependent current and voltage sources (VCVS,VCCS,CCCS,CCVS).

Not all components conversion is implemented. Now implemented only conversion of the Qucs circuit to Spice netlist.

With spice4qucs you can use good old spice to simulate Qucs circuits with it. Spice simulation results will be converted to Qucs simulation data and diagrams will be available from the display page. Spice simulation will be available after execution of this menu. I am planning to add menu entry Simulation->Simulate with spice. You can simulate your Qucs circuits with ngspice using this extension. This extension allows you to switch between qucsator simulation kernel and ngspice simulation kernel. I started implementation of spice4qucs extension. There may be way to overcome #34 and #41.
