Holger Vogt a165ab5c28 Allow Cd as a valid C reference designator for a capacitor, 
i.e. lower-casing of node names,
by re-organizing the setting of lower cases in the netlist:
No lower-casing for cd only while in a .control section.

Holger Vogt 7159d6aa4b 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 */

Holger Vogt e3bb6afb5d Add ifspec.ifs to MS Visual C project 2026-03-20 10:28:59 +01:00
Holger Vogt 81d3812db0 Add a user-settable variable measureprec to set the number of digits 
when printing the measure outputs.
Internally this is a global variable measure_precision.
Enable all measure commands to recognize measure_precision when
printing an output.
Default value is 5 (yielding 6 digits after .?).

Holger Vogt afb17cb6c7 New analogue and digital device models from TI contain 
the token GND in their subcircuit. Up to now ngspice has
declared GND as global and replaced it by 0.

Now, if PS is selected as compat mode, GND is not
declared as global, and is not replaced inside of a subcircuit.

Holger Vogt ab03cc94c0 Using mtimeavg 2026-02-03 14:23:41 +01:00
Holger Vogt b25ff08307 Moving window filtering with function 'newvec = mtimeavg(vec)' 
Window of fixed time width given by 'set mtimeavgwindow=400u'
Length and scale of newvec resembles the original vetor vec.
Large vec and large mtimeavgwindow take their time.
OpenMP is used if available.
