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

current

implementation alternatives

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):

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