Holger Vogt 06136d2d02 Set the default line width for grid and graph to 1. 
0 is possible but seems to be too thin for reasonable plots.

Holger Vogt 5083954fa1 Example input file for analog delay 2021-07-05 14:24:58 +02:00
Holger Vogt 028dd0ab88 Remove unused 
Add a delay of half a time step to reduce error
 2021-07-05 14:24:46 +02:00
Holger Vogt abc6eb56f3 Plausibility checking

Holger Vogt fbab9a0fe2 Add an analog delay source for transient simulation 
Internal circular memory of size tstop/tstep or user defined.
(aprox.) every tstep a value is stored.
Delay time in multiples of tstep, by control voltage or user defined.
Dc or ac sim will simply connect input to output.

Holger Vogt 4fd7de9e34 Partially re-introduce and improve code that has been 
inadvertently deleted in commit

83592c456 ("unify the evaluation of '.options scale=xx'
.option in a netlist will override 'options' from spinit,
.spiceinit or a script '.options scalm=xx' yields a warning,
it is not supported.", 2021-04-05)

The code transforms the option statements and adds them
to the current circuit.
