Periodic pulse source with not limited number of periods.

A single pulse is described by the following table:

time	value
0	I1
TD	I1
TD+TR	I2
TD+TR+PW	I2
TD+TR+PW+TF	I1
TSTOP	I1

Intermediate points are determined by linear interpolation.

A pulse it looks like a saw tooth, use this parameters e.g.:

Parameter	Value
I1	0
I2	1
TD	0
TR	1
TF	1
PW	2
PER	1

Note

• All parameters of sources should be set explicitly.
• since TSTEP and TSTOP are not available for modeling in Modelica, differences to SPICE may occur if not all parameters are set.

I1	Value: 0 Type: Current (A) Description: Initial value
I2	Value: 0 Type: Current (A) Description: Pulsed value
TD	Value: 0.0 Type: Time (s) Description: Delay time
TR	Value: Type: Time (s) Description: Rise time
TF	Value: TR Type: Time (s) Description: Fall time
PW	Value: Modelica.Constants.inf Type: Time (s) Description: Pulse width
PER	Value: Modelica.Constants.inf Type: Time (s) Description: Period
