Holger Vogt 933b1fdb2b Add some comment 2022-10-14 13:50:20 +02:00
Brian Taylor 150839dd1a Remove VisualC compile warnings. 2022-10-09 10:21:51 +02:00
Holger Vogt 7f486febe9 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 2547115eeb Prevent Visual Studio compiler warnings 2022-10-09 10:21:06 +02:00
Giles Atkinson e67261be29 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.

Make model more similar to LTSPICE
Add an example
 2022-10-08 16:50:38 +02:00
Holger Vogt 7bb581b1b3 Remove parameter noiseless in simple diode model. 
The model is noiseless anyway.
 2022-10-08 16:50:26 +02:00
Brian Taylor 266d944745 Remove unnecessary hierarchical level check. 2022-10-08 16:50:15 +02:00

Brian Taylor e2652d813d If ps_udevice_msgs >= 2, print complete line of unsupported PSpice instance. For debugging purposes. 2022-10-08 16:49:38 +02:00
Holger Vogt 4cb6c93a1a Add bidirectional bridge to MS project file for icm digital 2022-10-08 16:49:21 +02:00
Giles Atkinson c704854b3c Fix bug reported by Anant Devi in user discussion 22/9/22. 
A function call, vi(v) was misparsed as the special token i(vsource)
for the current in a voltage source.
 2022-10-08 16:49:02 +02:00
Giles Atkinson b212a49982 Add some automatic bridge examples, mostly using the bidirectional bridge. 2022-10-08 16:48:36 +02:00
Giles Atkinson d9952575dd Correct the digital state resolution table, that was previously asymmetric. 
An equivalent change is mentioned in the SPICE OPUS change history.
 2022-10-08 16:48:20 +02:00
Giles Atkinson 372d9b2c87 Add bidirectional digital/analog bridge. 2022-10-08 16:48:11 +02:00
Giles Atkinson e80b724460 Add two functions to the Code Model Library: cm_get_node_name() 
makes circuit node names available to diagnostics, while
cm_probe_node() is needed for a bidirectional A/D bridge.
 2022-10-08 16:47:50 +02:00
Giles Atkinson 8cc9d8522f 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.
 2022-10-08 16:47:30 +02:00
Giles Atkinson 06131d8107 Rewrite code with Visual Studio complaints. 2022-10-08 16:47:09 +02:00
Holger Vogt 56d07aab31 Transfer i(xx) to xxx#branch only when i is the first 
character of the token or preceeded by a space.
 2022-10-08 16:46:51 +02:00
Holger Vogt 92ba8ac88e Just to notify that this might need a better solution 2022-10-08 16:46:18 +02:00
Holger Vogt f832380dc9 FIXME: This is a hack to re-enable 'make check' 
Do not print warning if in batch mode.
 2022-10-08 16:46:01 +02:00
Holger Vogt 98763c0add 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.
 2022-10-08 16:45:38 +02:00
Holger Vogt 7483f6224d 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.
 2022-10-08 16:45:14 +02:00
Holger Vogt 6037450952 Warning message, when 'run' is called without job 
(tran, op, ac etc.) is defined.
 2022-10-08 16:44:48 +02:00
Holger Vogt 3af627db44 Change error messages to warning messages, because simulator moves on 
and command is ignored.
Make messages more verbose (which command?).
 2022-10-08 16:44:30 +02:00
Holger Vogt 1bcbe8e6d8 Don't send error message to stdout, but to stderr. 2022-10-08 16:44:01 +02:00
Holger Vogt 519ce44227 safeguard against circuit not being abvailable, 
avoid crash
 2022-10-08 16:43:41 +02:00
Holger Vogt 4713cf0bf7 add parameter description 2022-10-08 16:43:16 +02:00
Brian Taylor e703bd9142 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. 2022-10-07 13:48:37 +02:00
Brian Taylor e9855be595 If variable ps_port_directions >= 2, also show the translated Xspice statements. 2022-10-07 13:48:05 +02:00

Holger Vogt 0754ea7657 Make the Error message a Warning message, 
because ngspice may move on
 2022-10-07 13:38:20 +02:00
Holger Vogt 0af4932c6f Prevent a crash if (due to input error) the node_table is not available. 2022-10-07 13:37:57 +02:00
Holger Vogt 43c5ffaae8 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.
 2022-10-07 13:24:12 +02:00
Holger Vogt e6772f4e4e Prevent crash in gettok() and similar functions by checking for NULL 
input. Return NULL instead.

Holger Vogt 2126230b64 Prevent crashes when nodes or tables are not available, 
e.g. due to missing input file.
 2022-10-07 13:22:59 +02:00
Holger Vogt 037293c81e Improved error message: more info on the bad set form 2022-10-07 13:22:43 +02:00
Holger Vogt 26c687b088 enable evtcheck_nodes.c for MS Visual Studio 2022-10-07 13:21:02 +02:00
Giles Atkinson a0357b3432 Remove search for "family" parameters on subcircuits in XSPICE 
automatic bridging support as string-valued parameter support is
not yet intgrated.
 2022-10-07 13:20:34 +02:00
Giles Atkinson 4115064fd5 Latest auto-bridge code from development branch. 2022-10-07 13:20:17 +02:00
Giles Atkinson b1341c8e30 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.
 2022-10-07 13:19:59 +02:00
Holger Vogt 07bb809158 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.
 2022-10-07 13:19:22 +02:00
Holger Vogt d39c60542d Enable power measurement for W switch 2022-10-07 13:18:51 +02:00
Holger Vogt fe8eb26aaf Replace end-of-line comment delimiter $ by ; 
So to make it independent from compatibility switch selection.
 2022-10-07 13:18:29 +02:00
Holger Vogt 79bb8edc90 Allow individual current measurements in switches or 
linear dependent sources.
 2022-10-07 13:18:15 +02:00
Holger Vogt f1eb8d3955 examples for .probe alli or .probe i(xx) 2022-10-07 13:17:55 +02:00
Holger Vogt 7e610c8487 .probe alli improved: 
* Enable current mesurement for I source
* Look at only the first 2 nodes of S and W switches
and F and G controlled current sources, measure current
with = voltage source added to second node. So we get
I(Fx), I(Gx), I(Sx), and I(Wx).
