A method for analog circuits visualization

A method for the visualization of an analog circuit starting from a netlist is described in this paper. The images obtained have a comprehensible form, symmetrical structures and other analog topological patterns being discovered in the circuit netlist. The method is based on two algorithms. The first one, the symmetry algorithm, exploits the possibility of extracting topology information from a graph representation of the circuit. The second one performs a grid expansion on a directed graph structure, using the results of the symmetry algorithm. The method has been implemented in the "A-warD" program. Test-cases demonstrate the effectiveness of the method.
