 [badcrossbar] is a nodal analysis solver for passive crossbar arrays that suffer from line resistance. It solves for currents in all the branches, as well as for voltages at all the nodes of the crossbar. Additionally, it can create diagrams of crossbar arrays colored according to the values of those currents and voltages (or any other variables).

 # Background
 
 Conventional crossbars have a structure like the one shown in the image below. Resistive two-terminal **devices** (depicted here as memristors) are connected to **word lines** on one side and to **bit lines** on the other. In the diagram, the crossbar devices are depicted in black, the word lines are depicted as horizontal blue lines and the bit lines as vertical blue lines. Orange circles denote the **nodes**, i.e. the connections between the devices and the word/bit lines. The segments of word and bit lines between neighbouring nodes are often seen as **interconnects** between neighbouring devices and can themselves be modelled as resistive elements.
