|Model Name:||POP Trigger Schematic Device|
|Simulator:||This device is compatible with the SIMPLIS simulator|
|Parts Selector Menu Location:|
|Multiple Selections:||Only one POP Trigger device is permitted on a schematic.|
This symbol was introduced with version 8.0; however, the model and supporting files are available in version 7.20 as well. In versions prior to 7.20, the schematic will simulate, but you will not be able to edit the parameters with the dialog pictured in this topic.
For a version of the POP Trigger Schematic Device compatible with versions prior to version 7.20, see the parts selector entry:
Symbols placed on schematics in previous versions of SIMetrix/SIMPLIS can be automatically migrated to use the new symbols. The schematic tools menuwill invoke a routine which migrates the existing symbols to the new symbols. As this action makes substantial changes to the schematic, it is recommended that you save a backup copy of the schematic first.
The default parameter values for the POP Trigger Schematic Device are appropriate for most circuits. If you are experiencing simulator errors, the most likely cause is the POP analysis directives are not appropriate for your circuit. For more information, see the following topics:
To configure the POP Trigger Schematic Device, follow these steps:
Threshold (T) and Hysteresis (H) of the POP
Trigger Schematic Device. To determine the low-to-high threshold (TH)
and the high-to-low threshold (TL), substitute Threshold
(T) and Hysteresis (H) in each of the following
|Propagation delay||s||The propagation delay of the POP Trigger Schematic Device.|
|Divide by two?||Inserts a toggle flip-flop into the POP Trigger Schematic Device model. Primarily used for bridge converters, this allows you to use the master clock as the POP trigger source, the toggle flip-flop will produce a divided by two signal for the actual POP trigger gate used by SIMPLIS.|
|Trigger condition||Determines the triggering
condition of the input pin:
|Initial condition||The initial condition of the output when Divide by two? is checked.|
To edit the output Parameters, click on the Other Parameters tab. The parameters simply set the output levels for the POP Trigger Schematic Device. Changing these parameters will not help you circuit converge in a POP analysis, nor will changing these parameters affect the POP errors.
|Output high voltage||V||The high voltage of the output pin.|
|Output low voltage||V||The low voltage of the output pin.|
