Description
The Current PWL block is a source that generates a current by linear interpolation in a PieceWise Linear table (PWL).
The time points and current values are given as paired values, where the first given parameter contains the first time point and the second data contains the first current to be interpolated.
The table interpolation has the following properties :
• The time points need to be monotonically increasing
• Values outside of the table range are not computed by extrapolation through the last or first two points of the table, but computed from the last given point
