jean-pierre charras d4e5861c62 Fix a few issue in simulation (noticeable only when the calculation time is high): 
- Wait for end of simulation before return from "C" locale to current locale
(to avoid data files created by ngspice using curr locale instead of "C" locale)
- Do not allow changing signal list to plot during simulation calculation
(avoid crashes)

Seth Hillbrand 61289ab39a Cleanup ngspice calling signatures 2021-05-05 10:49:40 -07:00
Seth Hillbrand 36975c9cd0 Conditionally handle the SPICE signatures 
ngspice updated their function signatures, requiring us to test.  They
also don't provide an indicator that the signature is changed, so we
need to test based on the existence of a new version define.

onSimFinished() try to analyse the list of plots, but did not test
if there is available data before using it.

Including wx.h includes the full set of wxWidgets include files, that is not good,

Jeff Young 741481591e NetClass settings for Eeschema. 
ADDED Eeschema-specific netclass settings including wire and bus
thickness, color, and line style.

Netclasses override individual wire & bus colors and line styles.
If that proves an issue we might look at something more sophisticated
with inheritance.

Simon Richter f87dc08801 Readd <config.h> to ngspice.cpp 
This file should really be included first from any source file, because it
contains platform specific workarounds.

This also groups includes a bit by source.

Maciej Suminski b445b0fab2 Link eeschema with ngspice DLL 
Adds a link-time dependency for libngspice, so that other tools may
detect ngspice as a KiCad dependency.

The library is still loaded with dlopen() as it gives a way to reload it
in case of problems. The DLL name is recognized during CMake
configuration and used to load the library at runtime.

Stefan Brüns d1db2c7621 Use fixed version for libngspice.so.0 
CanonicalizeName only adds the lib prefix and .so suffix, so loading
libngspice.so fails until the development package is installed.
MAC/Windows code paths lookup soversion 0 of ngspice as well, as this
is the only compatible version.

Maciej Suminski 4526f40fe1 ngspice: add extra paths to search for libngspice 
The main purpose of the patch is to load libngspice from macOS bundle.
There are also some additional paths that could make Windows developers
easier.

Maciej Suminski bad462a228 Spice simulator: reload ngSpice dll on error 
ngSpice frequently ends up a simulation with an error:
"Error: ngspice.dll cannot recover and awaits to be detached"
The only way forward is to reload the shared library and
reinitialize ngSpice.

In case of problems, ngspice demands to be detached which is not
possible when it is linked at compile time.

Maciej Suminski 2a6b8f153b NGSPICE as a singleton 
One cannot call ngSpice_Init() twice without unloading the dll. When calling
ngSpice_Init, we pass a pointer to a NGSPICE instance and thus it cannot be changed.
When any of the callback function is called with a stale pointer everything crashes.
