Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Periodic pulse source with not limited number of periods.
A single pulse 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.
A pulse it looks like a saw tooth, use this parameters e.g.:
Parameter |
Value |
V1 |
0 |
V2 |

TR |

PER |

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.
