Giles Atkinson d86a0c77cb Improve scheduling of breakpoints for V-source (PULSE and PWL). 
This fixes bugs with the TRA delay line reported by Tom Hajjar in
the Help forum, Jan 11 2024.

Giles Atkinson 2ad97feb31 A quick fix for a bug reported in the Help forum by Tom Hajjar on 
Jan 6 2024.  Prevent the TRA device from requesting a breakpoint
in the past, as that is a hard error.

Holger Vogt e6d6f8e928 Update to V/I sources, SFFM and AM 
Enable more AM functions.
Unify the settings of both sources.
 2024-01-08 13:21:43 +01:00
Holger Vogt 5dbb25f667 Set new default values. 
Restructure the code a bit.

Two parameters for AM are required (offset and amplitude). Even if this
sounds needless, changing it would require a major effort.

Holger Vogt 88d0727d3f In PS compat mode we only have 2 nodes in a diode, 
but still allow self heating diode with ngspice syntax.

Holger Vogt c1effe3b33 Just a hack to avoid a crash during sensitivity analysis: 
Exclude parameter RCO from sens code, if not given,
as sens sets mods->BJTintCollResistGiven to TRUE, which fails due to
missing memory allocation for the extra nodes.

Holger Vogt db5e5b08eb Don't switch display to "op", if called from a dc simulation. 2023-12-22 18:16:26 +01:00
Holger Vogt 03905433bb If compatmode hs is set, don't run an extra iteration with 
differing mode settings, but go directly to CKTop().
If other or none compat modes, keep existing behavior, as
for example CIDER example may otherwise slow down significantly.

This is to keep dc sim in accordance with other simulators.

Holger Vogt 37944bd7c4 Preliminary fix to bug 650

Giles Atkinson af31904f99 The previous fix for Bug #467 - ".OPTION INTERP has accuracy issue" 
(359e3d46) updated variable timeold inside a loop so that
all interpolations after the first caused division by zero.
That caused the xspice/delta-sigma example to fail.
Set the variable once at the end of the function.

Giles Atkinson ffcf3b24d9 Improve efficiency and irreversible CM support in EVTcall_hybrids() by 
halting calls to code models as soon as the timestep is chenged.

Holger Vogt 45850c07dc Don't silently accept wrong user input (missing nodes, values). 
Check for at leat 4 tokens (name, n1, n2, val/model/...).

Giles Atkinson d82f948832 Fix a crash found by Brian Taylor: when .plot attempts to plot digital 
node history, interpolation may produce an infinite value at digital edges.
Remove vertical edges when interpolating and make some other improvements:
do not calculate a polynomial approximation for unused frames;
center the target x-value in the frame; and do not propogate a reduction
in degree to later frames.

Giles Atkinson c18447f9f5 Add the support files for co-simulation with Verilog code 
compiled by Verilator.  Also add script files to Visual Studio builds
that are already installed by the Makefile builds.

Giles Atkinson 597268cc26 Treat input files names passed a start-up the same as those entered 
as commands or called as scripts: search for them using $sourcepath.

Giles Atkinson 07ce9c788e Recognise *ng_script_with_params" in the first line of the first 
program input file to mean that the file is a pure interpreter
script that receives any remaining command arguments.
In winmain.c ensure that the argv array is NULL-terminated
and tidy some code.

Giles Atkinson 89851872ed When substituting interpreter variables, allow '$' to be part of 
the variable expresstion only within '[]' or '()'. That lets
forms like "$a$b" to be treated as two substitutions, not one.
