Giles Atkinson ad5bb9eb8d Fix Bug #607 -
"DC Source with Pulse stops pulsing half way through simulation".
Do not require breakpoints to be hit almost exactly before scheduling
the next one.  That may cause the next breakpoint to be lost.

Holger Vogt d53acbed8e Add noise capability to XSPICE code models
Coded according to acan., AC analysis

MIF_NOI is not yet supported by any code model, so
MIF_AC is used (code models behave like in ac mode,
they are noiseless.

Pascal Kuthe acfaf023b3 prototype for Verilog-A integration using OSDI and OpenVAF
This initial prototype is capable of performing DC, transient and AC
analysis. Not all features of OSDI are supported yet and there are still
some open questions regarding ngspice integration. However many usecase
already work very well and a large amount of CMC models are supported.
The biggest missing feature right now is noise analysis.

test: test case for diode DC working with SH

test: add transient analysis to osdi_diode test

test: added docu text to osdi_diode test

test: added test case directories

fix: bug in osdi_load

test: small change to netlist

fix: implement DEVunsetup

fix: correct behaviour for MODEINITSMSIG

test: osdi diode enable all analysis modes

removed netlist

ignoring test results

added the build of the diode shared object to the python test script

deleting old stuff and always rebuilding the shared object

added diode_va.c to the repo

preparing CI

Create .gitlab-ci.yml file

(testing) add res, cap and multiple devices test

feat: use osdi command to load files

Previously OSDI shared object files were loaded from fixed directories.
This was unreliable, inconvenient and caused conflicts with XSPICE.

This commit remove the old loading mechanism and instead introduces the
`osdi` command that can load (a list of) osdi object files (like the
codemodel command for XSPICE). A typical usecase will use this as a
precommand in the netlist:

.control
pre_osdi foo.osdi
.endc

If the specified file is a relative path it is first resolved relative
to the parent directory of the netlist. If the osdi command is invoked
from the interactive prompt the file is resolved relative to the current
working directory instead.

This commit also moves osdi from the devices folder to the root src
folder like xspice. This better reflects the role of the code as users
may otherthwise (mistakenly) assume that osdi is just another
handwritten model.

test: update tests to new command

fix: do not ignore first parameter

feat: implement log message callback

fix: don't generate ddt matrix/rhs in DC sweep

fix: missing linker script

update to osdi 0.3

(testing) simplify test cases, fix bug

(testing) multiple devices test improvement

(testig) node collapsing bugfix

test: increase tolerance in tests

feat: update to newest OSDI header

fix: temperature update dt behaviour

fix: ignored models

fix: compilation script

fix: allow hicum/l2 to compile with older c++ compilers

fix: set required compiler flags for osdi

fix: disable x by default

fix: add missing SPICE functions

fix: update diode to latest ngspice version

feat: implement python CMC test runner

doc: Add README_OSDI.md

fix: make testing script work with python version before 3.9

fix: free of undefined local variable

fix: do not calculate time derivative during tran op

update osdi version
