XOR gate

The XOR gate's PoPs output activity should be correlated to the PoPs input activity as shown in the picture:

 input A ^
         | H  D  L
         | D  D  D
         | L  D  H
         +--------->
            input B

 output: High, Low, Dont care

modeling

we are interested in the input/output behavior at steady state, that is when the system has reached equilibra and the concentrations of concerned species don't change anymore. since we have 2 inputs and 1 ouptut, simulation results will be illustrated as a surface plot, inputs on the x/y axes and output on the z axis.

ideal xor gate

the expected input/output behavior of an ideal xor gate looks like this (with less green being better):

behavior of an ideal XOR gate, topside view
behavior of an ideal XOR gate, 3d surface plot

note that the anterior low (blue) part has low inputs, the rear one has high inputs.
