pvcvs

Hi,
I want to know the use of PVCVS component in Cadence analogLib.
When I used it in a circuit simulation, but it failed because of the setting of PVCVS.
I want to find the guide o f it, but there is nothing to be value in the introduction of the analogLib.

I want to use it the follow the source of input port, but I don't know how to set it and what are the meaning of every port of this component.

The introduction of it is as follow:

Polynomial Voltage Controlled Current Source

A polynomial voltage controlled current source in which the symbol varies with the number of controlling voltages. A vector of coefficients specifies the polynomial function that defines the relationship between the output current and the controlling voltages. You must specify at least one coefficient.

For a polynomial in M variables a1, a2, ... am, the polynomial function F(a0,a1,...,am) is given by:

F = c0 + c1 * a1 + c2 * a2 + ...

+ c(m+1) * a1^2 + c(m+2) * a1 * a2 +...

+ c(2m+1) * a2^2 + c(2m+2) * a2 * a3 +...

where the 'c's are coefficients of the polynomial terms.

Thank you!
Best regards
