Holger Vogt 0be163d8d8 Search for "off" token in device instance lines not with
C standard fcn strstr, but with search_plain_identifier().
Thus allow model names that contain "off" (like offset)

Holger Vogt d04445e085 When calculating power, we need to exclude thermal nodes
of devices like diodes (d) and MOS (m)
2022-04-26 10:35:56 +02:00
Holger Vogt 2fabc53f4f Add flag 'power' to fcn setallvsources()

(top level instances, including X (subcircuit) invocations).
2022-04-26 10:35:44 +02:00
Holger Vogt a165556088 revert polarity of current mesurements:
current positive when flowing into device, e.g.
Ic, Ib of a positively biased npn.

Add current measurement for all nodes of a device,
e.g. .probe i(Q1) will measure Ic, Ib, Ie (and Is)

Giles Atkinson 39b837a405 Fix Bug #402 "Crash related to aliases". Do not return freed pointer. 2022-04-26 10:34:45 +02:00
Holger Vogt 16f619818e Remove a conflict between the text variable substitution like
set text = "mytext"
set newtext = new.{$text}
echo $newtext
and the command circbyline, which may have to process strings
containing braces {...} without any change to the string.

Do not call cp_doglob() when command circbyline is executed.

Holger Vogt 2915f8e991 In case of resistor valuues r150 (r + integer number),
return 150
R2 n1 n2 r150

In case of r23mod return error = 1 and val = 0, so
r23mod may be read as a model, not an instance parameter
R3 n3 n4 r23mod

Giles Atkinson 9ac4dab81a Fix two crashes caused by trying to plot after circuit parsing failed. 2022-04-26 10:32:47 +02:00
Giles Atkinson c65155880c Make "nogrid" plotting option work. The deleted code was in the original
commit, so the reason for it can not be traced.
2022-04-26 10:32:39 +02:00
Holger Vogt 26c50de68b function deriv: This is just a preliminary fix: prevent a crash
when base > 0.

But when is base supposed to be > 0 ? More invetigation is needed.

With this commit the patch provided by Alessio Cacchiatori the S-parameter is completed:
Noise simulation added with C matrix output
Y and Z matrix output enabled

To allow compiling with gcc, the dense.h inline functions have been put into denseinlines.h

Holger Vogt 20d5919e59 Terminal setting to X11 fails in macOS, and is not required
on Linux.
Setting terminal here is redundant, so remove this setting.

Holger Vogt 12a93c9fe6 Update to plotting of event nodes:
Distance is now 1.5, scaling and cutouts are possible
(with some lack of precision).

Still missing: y axis labeling (no numbers, but node names).
2022-02-21 20:19:56 +01:00
Holger Vogt 342a16d6e1 Add a flag 'alle' (all event nodes) to the plot command (and maybe others).
All event nodes with length greater than 1 are translated to vectors
with a common scale (named step) and are assembled in a new plot
named 'digital'. They may be plotted or otherwise used in a
.control section.
