    <description>The model describes a PWL voltage source in the same way as in SPICE<br></br>(SPICE3 Version 3f3 User's Manual). The parameter WAVE is a one<br></br>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>
