The exported SPICE netlist file cannot be successfully simulated

[David Cat]

When I simulate the circuit using KiCAD V7.99, it is successful. However, when I export the netlist file and simulate it using the ngspice, the simulation fails.
Steps for ngspice simulation:
1. source file
2. run
All the files used for reproduction are attached.
 Are there any special parameters set by KiCAD during simulation?In theory, the exported netlist file should also simulate successfully using ngspice, or is there an issue with the exported netlist?

There are some settings that KiCad will pass to ngspice depending on your configuration.  These are mostly compatibility flags.

However, as a developer mailing list, we're mostly interested in developing KiCad.  It sounds like you are having some trouble using either KiCad or ngspice.  We have user forums for how to use KiCad and ngspice has an ngspice-user mailing list that can help you out with how to use either program.
