General form:

FXXXX N+ N- POLY(ND) V1 (V2 V3 ...) P0 (P1...)

Example:

FNONLIN 100 101 POLY(2) VDD Vxx 0 0.0 13.6 0.2 0.005 

POLY(ND) Specifies the number of dimensions of the polynomial. The number of controlling sources must be equal to the number of dimensions.

(N+) and (N-) nodes are output nodes. Positive current flows from the (+) node through the source to the (-) node.

V1 (V2 V3 ...) are the controlling voltage sources. Control variable is the current through these sources.

P0 (P1...) are the coefficients, as have been described in 5.5.1.
