Holger Vogt 96f4a85fc2 Merge branch 'pre-master-46' of ssh://git.code.sf.net/p/ngspice/ngspice into pre-master-46 2026-03-26 16:15:40 +01:00
Holger Vogt 4ec701b43e Prevent a crash with shared ngspice when memory is exhausted: 
Add a pre-check if available memory is sufficient. If not, bail out.

Holger Vogt ab5010506e A memory leak occurs when command 'step' is followed by 'quit' 
without having reached the final TSTOP.
New function DCtran_step_quit() removes the leak.

Ralf Habacker 2d9e42669b Add command line support for the 'version [-s|-f]' command 
With this commit the mentioned ngspice command(s) are
also available on the command line. See ngspice --help
for more information.

Holger Vogt 7482de588b Parameter np=xx added. xx may be a number or auto2n. 
If np is not set, 'linearize' behaves as usual, (TSTOP-TSTART)/TSTEP + 1.5
If np=<number>, integer <number> is used
If np=auto2n, the number of points is 2^n, close to (TSTOP-TSTART)/TSTEP.

dwarning f7ef88b637 Diode soft recovery model based on the idea of A. Buermen with iterated charge node for diffusion charge and model parameter Vp. 
Small simplifications in AC model and capacitance reporting are made. No self-heating for this effect. Pole-Zero and distortion
analysis is not implemented for this model extension.

Holger Vogt 6c8ab82e9e V Pulse delivers erratic outputs, when not parameterized properly. 
Update the pulse generation: negative TR, TF, PW, PER not possible,
get default values instead. 0 PW is allowed.

Defaults are:
TR negative or 0 --> TR = ckt->CKTstep
TF negative or 0 --> TF = ckt->CKTstep
PW < 0 --> PW = 0
PER <= 0 --> PER = TR + TF + PW */
