Enrique 04507a637d Added parameter numPeriod so that the user can select the number of fundamental frequency periods used in the detection of the fundamental frequency and its harmonics. This is usefull when trying to recover the fundamental frequency and its harmonics from a noisy signal, like the output of a DCDC converter 2026-02-26 23:12:36 +01:00

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 */

Holger Vogt d163db99c7 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 82e563b1b1 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 14363ba45a 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.

Holger Vogt 99bddad736 Enable optional voltage based truncation error correction. 
This is selectable as 'option newtrunc' (--enable-Predictor is required)

Remove --enable-NEWTRUNC

Add three option parameters (default):
lteTrtol (500), lteReltol (1e-3), lteAbstol (1e-6)

Add new error function for TRAP, similar to GEAR
 (tentative, to be improved), in ckttrun.c

Enable PREDICTOR as default with Visual Studio.
