Net functions represent the propagated instances of output functions as they travel along nets.Net functions are automatically created by the eXpress software, as output functions actively or passively propagate the signals received from their dependent inputs onto the nets that are connected to their associated output ports.
The specific number of net functions that appear on each net is based upon a variety of factors, including the number of output ports connected to the net, the number of output functions on each of these ports, whether these functions are propagated actively or passively, and the number of source signals recieved by the input port dependencies of each of these output functions. Although the Analyst cannot explicitly create or remove net functions, signal flow(the propagation of net functions through the system) can nevertheless be constrained by editing the input port dependencies of individual output functions or the net function dependencies of individual input functions.
Whenever functions are re-propagated, existing net functions are replaced by newly-generated functions and existing input filters may become out-of-date.
