Simulator Spontaneously Closes when ibis-test is Invoked

Schematic Simulation (Ngspice)
1

Hello,

In KiCad 9.0 on Windows 10, I’m experiencing a spontaneous close of all KiCad windows upon clicking any analysis or run icon in the SPICE Simulator window. Steps to reproduce:

  1. Download ibis-test.7z from this post: Simulation examples for KiCad8/KiCad9/Eeschema/ngspice
  2. Open KiCad project ibis0.kicad_pro
  3. Open the schematic and save it to update it to version 9.0
  4. Click the Simulator button in the schematic editor
  5. SPICE Simulator window opens…
  6. Click Edit Analysis Tab button and all KiCad windows stop responding. After about 20 seconds, the simulator and schematic windows spontaneously close. The KiCad project window remains open and responsive.

Note that I’ve had success with many of the simulation examples located here:

Any ideas?

Thanks,

Rob

I can reproduce this behaviour in KiCad 8.0.9 and 9.0 as well. The crash seems to happen outside of ngspice (in Eeschema?). It is worth a bug report.

Thanks Holger.
