General form:

GXXXXXXX n+ n- cur='expr' <m=val>

Examples:

G51 55 225 cur = 'V(3)*V(3)-Offs'

Expression may be an equation or an expression containing node voltages or branch currents (in the form of i(vm)) and any other terms as given for the B source and described in Chapt. 5.1. It may contain parameters (2.8.1) and special variables (5.1.2). m is an optional multiplier to the output current. val may be a numerical value or an expression according to 2.8.5 containing only references to other parameters (no node voltages or branch currents!), because it is evaluated before the simulation commences.
