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.

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.

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.

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.

Holger Vogt 7483f6224d Note: vs: dc value used for op instead of transient time=0 value

(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?).

2022-10-07 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.

Giles Atkinson a0357b3432 Remove search for "family" parameters on subcircuits in XSPICE
automatic bridging support as string-valued parameter support is
not yet intgrated.

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.

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.

Holger Vogt fe8eb26aaf Replace end-of-line comment delimiter $ by ;
So to make it independent from compatibility switch selection.

Holger Vogt 79bb8edc90 Allow individual current measurements in switches or
linear dependent sources.

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).

Brian Taylor 3ca91aa1ac Make a trivial change to support (n)and3a, (n)or3a, (n)xor3a types. These are not used in any of the Micro Cap libraries. Completes support for Pspice tristate gate types. 2022-10-07 13:15:45 +02:00
Brian Taylor 4706c3dea5 Add 74xx283 4-bit adder example from the Micro Cap digital example circuits. Pspice primitives are translated to Xspice and a waveform is displayed using GTKWave. This is a digital-only test. 2022-10-07 13:15:23 +02:00
Brian Taylor abd4af1ae6 Ignore IO models in a subckt. Setting variable ps_port_directions to a non-zero int prints the directions (IN, OUT, INOUT) of subckt ports. 2022-10-07 13:14:58 +02:00
Brian Taylor 2d9f86c742 Check for name collisions between nodes generated during translation from Pspice to Xspice and instance pin or subckt port names. These are reported as ERRRORs. 2022-10-07 13:14:35 +02:00
Holger Vogt e9b5a9a957 aswitch needs two input nodes because gd has been selected for input. 2022-10-07 13:13:38 +02:00
