Giles Atkinson b3fd63ea88 Fix numerous gcc warnings of duplicate declarations. 2022-04-26 10:34:52 +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

The syntax is listed in the ngspice manual,
chapter 17.6 Control Structures. Practical examples
using a simple voltage divider circuit are given here.

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

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).
