PWL (T1 V1 <T2 V2 T3 V3 T4 V4 ...>)
Example:
VCLOCK 7 5 PWL (0 -7 10NS -7 11NS -3 17NS -3) VNEW 1 0 PWL (0 0 10NS 1 50NS 5 90NS 5)
Parameters and default values:
Each pair of values (T1, V1) specifies that the value of the source is V1 (in volts or amps) at time=T1. The value of the source at intermediate values of time is determined by using linear interpolation on the input values.
