The one-transistor-one-RRAM (1T1R) cell structure is eventually adopted as one basic synaptic weight to suppress the sneak path
and improve the conductance modulation.
But you found a sneak path
that looks like it might work, and it's still on grid.
In other words, whether the spectral component in question came directly from a frequency source, or was generated through a sneak path
of several mixers and subsequent amplification, SPECTRASYS identifies the component origin.
There is only one return path through each channel ground and no sneak path
or short circuits.
The CoFI  methodology guides the tester to depict the system behaviour into different classes: normal behaviour, specified exceptions, sneak paths, and fault tolerance.
In the following, Step 2 aims at complementing the state machine with the sneak paths' transitions, which represent the behaviour of the system when receiving unexpected inputs.
The model with the sneak paths' transitions is presented in Figure 9.
Poor matching can seriously degrade a device's spurious performance while uncontrolled ground currents, sneak paths
and waveguide moding can cause high level internal and external spurious responses.
