[dsm]

Hi, will this library add for qucs_s with ngspice ?

Can MOC3052 and MOC3063 be added from https://fotoelektronika.com/spice-models/ ?

Yes, the Optocoupler.lib could be extended. I have added this task to #846

@ra3xdh how I can use this in qucs_s psice library

[ra3xdh]

The best way is to use Spice Library device See the chapter 8.2 of the latest Qucs-S tutorial: https://ra3xdh.github.io/pdf/qucs_s_tutorial.pdf There exists symbol patterns for thyristor devices.

The works on extension of this feature have been planned. See #944

@ra3xdh thanks.

I have added generic ST Triac model in Thyristor.lib by #1197. New device is named TriacGeneric. But I failed to port this device to pure Ngspice syntax. This device requires setting the LTSpice compatibility mode in Simulation->Simulator settings
