Title: Learning to use QUCS-s
Post by: sidereal on January 15, 2023, 02:52:06 pm
Hi

I am trying to learn how to use QUCS-s on linux with ngspice backend.

My simulation is attached. I am trying to add a DC simulation of a simple transistor powered RC oscillator circuit.  However, I get the error

Ngspice started...
Error on line 11 or its substitute:
  q2 v2_out _net2 0 1
could not find a valid modelname
    Simulation interrupted due to error!

Note: No ".plot", ".print", or ".fourier" lines; no simulations run

Note: No compatibility mode selected!



A picture of how I set out the simulation is also added.

Can anyone please tell me where I am wrong? Thank you.
