Adding a startup (or ramp) time to independent voltage and current sources.
|
||
|
|
|
||
|
|
By adding a flaG 'startup' to the 'tran' command, all independent current
|
||
|
|
and voltage source outputs are scaled by the factor time/StartupTime if
|
||
|
|
simulation time is smaller than StartupTime. Thus they are ramped up
|
||
|
|
linearily between times 0 and StartupTime.
|
||
|
|
|
||
|
|
The default value of 20us may be overridden by adding a line
|
||
|
|
set startup_time = <value>
|
||
|
|
to .spiceinit (or to the top of a .control script), where <value> may
|
||
|
|
be any valid ngspice real number representing time. Negativ or 0 entries
|
||
|
|
are ignored.
|
||
|
|
|
||
|
|
Code changes include introducing a new mode flag MODESTARTUP and the
|
||
|
|
scaling in vsrcload.c and isrcload.c.
