parameter | default value | units
|
V1 (initial value) | Volts or Amps
| |
V2 (pulsed value) | Volts or Amps
| |
TD (delay time) | 0.0 | seconds
|
TR (rise time) | TSTEP | seconds
|
TF (fall time) | TSTEP | seconds
|
PW (pulse width) | TSTOP | seconds
|
PER(period) | TSTOP | seconds

A single pulse so specified is described by the following table:
time | value
|
0 | V1
|
TD | V1
|
TD+TR | V2
|
TD+TR+PW | V2
|
TD+TR+PW+TF | V1
|
TSTOP | V1
|
Intermediate points are determined by linear interpolation.
