Holger Vogt 540cda52ad If compatmode is lt, change the pow(x,y) and x**y functions: 
If x < 0, output only if y is integer number, otherwise output 0

Brian Taylor ff58fbbe56 Remove VisualC compile warnings. 2022-10-09 10:15:14 +02:00
Holger Vogt 317e5a3d99 Search for .spiceinit (or spice.rc) firstly in a user defined directory, 
when the directory path is set in the environmental variable
SPICE_USERINIT_DIR.
If not found then search in the current directory, then in HOME, then
in USERPROFILE.

Holger Vogt dcb3bf0f8b Prevent Visual Studio compiler warnings 2022-10-08 17:20:48 +02:00
Giles Atkinson 8775376723 Fix a crash that sometimes occurs on Linux when interrupting from 
the terminal a simulation that was started directly from the command
line.  A gdb backtrace showed rl_cleanup_after_signal() calling
fwrite() with a NULL file pointer.

for the current in a voltage source.
 2022-09-23 13:15:07 +02:00

Giles Atkinson 31fcd7d561 Correct the digital state resolution table, that was previously asymmetric.

Giles Atkinson 118b997642 Add two functions to the Code Model Library: cm_get_node_name()

cm_probe_node() is needed for a bidirectional A/D bridge.
 2022-09-23 13:15:07 +02:00
Giles Atkinson 9d780f8bb4 Fix bug #602 "Warning message trying to linearize a transient analysis vector" 
by changing the way "ngspice -a" (autorun option) works.  The inserted code
now checks whether a simulation has already run by examining $curplot
before forcing "run".  Also at most one simulation is forced to run.

Holger Vogt 2d4c1379af Transfer i(xx) to xxx#branch only when i is the first 
character of the token or preceeded by a space.
 2022-09-23 12:58:47 +02:00
Holger Vogt c7b0438ce7 Just to notify that this might need a better solution 2022-09-23 12:04:20 +02:00
Holger Vogt 41e92be956 FIXME: This is a hack to re-enable 'make check' 
Do not print warning if in batch mode.
 2022-09-21 10:04:22 +02:00
Holger Vogt cfba8a5cd3 Note: ix: dc value used for op instead of transient time=0 value 
Former warning message or note only issued when dc value and
value at transient time=0 differ.
 2022-09-20 22:50:17 +02:00
Holger Vogt bce48859df Note: vs: dc value used for op instead of transient time=0 value 
Former warning message or note only issued when dc value and
value at transient time=0 differ.
 2022-09-20 22:47:24 +02:00
Holger Vogt ba394d5903 Warning message, when 'run' is called without job 
(tran, op, ac etc.) is defined.
 2022-09-20 20:09:42 +02:00
Holger Vogt 6237639ec5 Change error messages to warning messages, because simulator moves on 
and command is ignored.
Make messages more verbose (which command?).
 2022-09-20 13:28:55 +02:00
Holger Vogt 64b429d6f8 Don't send error message to stdout, but to stderr. 2022-09-18 16:00:21 +02:00

Brian Taylor 78f732a8a1 Add comment about ps_udevice_msgs variable. Set to 1 will print PSpice instance names and types which are not supported and are found when processing a subckt. 2022-09-14 15:01:39 +02:00
Holger Vogt fb75a15e83 example for pwlts source code model 2022-09-09 15:26:45 +02:00

Holger Vogt f5a172ce4e Make the Error message a Warning message, 
because ngspice may move on
 2022-09-07 16:27:29 +02:00
Holger Vogt 8ef0c03fa6 Prevent a crash if (due to input error) the node_table is not available. 2022-09-04 17:35:47 +02:00
Holger Vogt c7fa70d109 Add special savecurrents options: 
options savecurrents_bsim3, savecurrents_bsim4, and savecurrents_mos1
will save all device currents as listed in chapts 31.6.1, .8 and .9
of the ngspice manual. Pure savecurrents will yield a subset of MOS1
currents, as seen before.
 2022-09-02 15:06:40 +02:00
Holger Vogt e9fcb9b332 Prevent crash in gettok() and similar functions by checking for NULL 
input. Return NULL instead.

not yet intgrated.

Giles Atkinson 495172f532 Latest auto-bridge code from development branch. 2022-08-31 15:34:04 +02:00
Giles Atkinson 148cecf919 Insert XSPICE bridging devices automatically when an analogue node 
has the same name as an XSPICE event node (including digital nodes).
The function Evtcheck_nodes() is replaced by a new version in its
own file.
 2022-08-31 15:33:59 +02:00
Holger Vogt ff62468c1f Iterations for op or dc may start with arguments 0 for ln(). 
To cope with this, and potential overflow in exp function,
some limits have been added.
