POP Advanced Options
Press the Advanced... button for more POP options. The following dialog opens:
| Parameter | Description |
| Convergence | Sets the convergence criteria for the periodic operating point analysis. The convergence criteria is satisfied when the relative change in each state variable, between the start and end of a switching cycle, is less than this parameter. All state variable must have a relative change lower than the convergence criteria for the POP run to converge. This parameter is expressed in percent. |
| Iteration limit | Iteration limit: Sets the maximum number of iterations for the periodic operating point analysis. |
| Number of cycles output | After a successful POP analysis, and if there is no transient analysis specified, SIMPLIS will generate the steady-state time-domain waveforms for an integral number switching cycles. This option sets the number of cycles to output and can be between 1 and 16. |
| Use snapshot from previous transient analysis | If checked, POP is instructed to take advantage of the last data point of a previous transient simulation, assuming the circuit and the initial conditions remained the same between the two simulation runs. |
| Output POP progress | If checked the progress of the POP solution will be output to the data file for plotting and subsequent debugging. |
| Define transient after failed POP | If a POP analysis fails to converge, you have the option to automatically start a subsequent transient analysis. This is useful to help diagnose the cause of the POP failure. |
| Enable automatic transient analysis after a failed POP | Check this box to enable this feature. The transient analysis will run for 100 x POP period by default. To change this, click on Specify then enter the desired period. |
