KiCad 7.0.1 Crash with simulation

Schematic Simulation (Ngspice)
1

Application: KiCad x64 on x64

Version: 7.0.1, release build

Libraries:
wxWidgets 3.2.2
FreeType 2.12.1
HarfBuzz 5.0.1
FontConfig 2.14.1
libcurl/7.83.1-DEV Schannel zlib/1.2.13

Platform: Windows 10 (build 19044), 64-bit edition, 64 bit, Little endian, wxMSW

Build Info:
Date: Mar 11 2023 03:41:46
wxWidgets: 3.2.2 (wchar_t,wx containers)
Boost: 1.80.0
OCC: 7.6.2
Curl: 7.83.1-DEV

Compiler: Visual C++ 1934 without C++ ABI

Build settings:
KICAD_SPICE=ON

OS : Windows 10 Enterprise 21H2 build 19044.2728

KiCad crashes immediately as soon as I select ‘Start simulation’

Do you have a symbol in your schematic that does not have a SPICE model defined? That might cause this behaviour; fixed in 7.99 and will be fixed in 7.0.2.
If that is the case, assign a proper model and configure it properly, and it should work.

3

Unfortunately everything is set properly…KiCad crashes and its window is immediately closed. Tomorrow morning I will test the same circuitry on another computer (same OS but different build)

4

I see that I mistyped above. I meant to say that there might be a symbol that doesn’t have a SPICE model properly defined or missing a SPICE model…

5

Will check tomorrow…thanks a lot !

6

ERC indicates that my generic op amp +15v & -15V pins are not connected. I’m actually struggling to fix this…

7

ERC has now only warnings but simulation crashes the entire KiCad program

8

Sorry but is Kicad able to read .cir file when I set the simulation model ? Or do I need to convert this type of file to .lib or to .sub or to .ibs
