Hello Shalini,

You're describing placing a V-source in parallel with an I-source.  I don't
know if
this is what you want, because the V-source (unless you specify a non-zero
output impedance) will effectively suck up all of the current from the
I-source,
and the net current going out of or into nodes 1 and 2 will be determined by
the rest
of the circuit hooked up to these nodes, not the V-controlled I-source.

Regards,
Drew

                      I have to model a voltage
controlled current source, problem is that the
                      controlling node is the same as
the node across which this VCCS is
                      connected something like this. [
it's a kind of non-linear resistor too.]

                      GXXX 1 2 1 2
value{sin(v(1)-v(2)}

                      but somehow this sentence gives
syntax error.
                      I am simulating in spectreS
(similar as hspice) environment.

                      Any clue why this shows syntax
error.
