Re: [Qucs-devel] Qucs in power electronics course

[Claudio G. <cla...@vi...>]

Hello Luigi,
at the moment there is no plan to add a solver using piecewise-linear 
models.
Moreover, at present the transient simulation in Qucs is not very 
robust, as you will surely have noticed already. Also here there are 
some ideas for improvements but little time for the actual 
implementation.

In the meantime a good solution could be to use a Qucs derivative, 
Qucs-S, which can use ngspice, Xyce or Spice Opus as simulation 
engines. The plan is to merge the functionality of Qucs-S (and more) to 
Qucs in the future.
A description of Qucs-S can be found at https://qucs-help.readthedocs.
io/en/spice4qucs/index.html
Binary packages and source code are available at https://github.
com/ra3xdh/qucs/releases/tag/0.0.19S

Hope this helps,
regards,
  Claudio
