Notes
The content of the sub-circuit file (SINI.ckt) associated with this model is shown below. The formula/equation used to provide this function is declared as part of the netlist-specific entry, under the .SUBCKT line of the file.
*Sine of Current
.SUBCKT SINI 1 2 3 4
VX 1 2 0
BX 4 3 I=SIN(I(VX))
.ENDS SINI
The resulting current is the value expressed in radians.
Examples
Consider the circuit in the image above. With respect to the SINI component, the entries in the SPICE netlist will be:
