Holger Vogt 8e80933cfa If XSPICE is not selected, still send CKTspDump(ckt, freq, spPlot), 
but without ipc (spPlot instead of undefined acPlot)

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)

(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)
 2022-04-26 10:35:29 +02:00

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 287406459a Make error message more verbose 2022-04-26 10:33:41 +02:00
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

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.
