Brian Taylor a70297e87a Several PSPICE 9.1 evaluation digital libraries contain timing .model statements at the global level for subckts with U* instances that reference those models. By specifying "set ps_global_tmodels=1" in .spiceinit an extra pass inside u_instances() will collect those global timing models for use in subckts. Report errors detected when ngspice parses a LOGICEXP but has not added support for operator precendence. Include a hint of how to fix those errors by inserting parentheses. This error only occurs in 10 of 585 cases in the libraries. Note that inpcompat.c has been saved as a unix filetype. 2024-01-17 14:15:07 +01:00

Holger Vogt 79e80dbbab Automatically adding diode RS only when variable 'rsdiode' is set 
to a positive resistance value.

Holger Vogt 0141473aa4 Don't derefence Matrix->SMPkluMatrix->KLUmatrixCommon if it is NULL. 
Test for NULL moved upwards in front of dereferencing.

Holger Vogt 5266a7c4bc If there is a successful step, but the goal is not yet reached, 
don't start with the minimum value of 1.00005, as this may last
forever. Restart with 3.

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 fb76eb5e12 Example for V/I sources, SFFM and AM 2024-01-08 13:24:01 +01:00
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.

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 
Don't omit replacement, when independent nested subcircuit has been checked.
FIXME: Better use the cards level parameter.

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 81351555da Mention the vlnggen script and Verilog-controlled XSPICE models. 2023-12-19 14:27:12 +01:00
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.
