    <description>The model describes a PWL nonconservative source in a similar way as <br></br>a SPICE piece-wise independent voltage source. The parameter WAVE is <br></br>a one dimensional real array with time value pairs T1, V1, T2, V2, ... <br></br>Each pair of values Ti, Vi specifies that the value of the source <br></br>is Vi at time Ti.  The value of the source at intermediate values <br></br>is determined by using linear interpolation. The times must be given <br></br>in ascending order.<br></br></description>
