Voyeur - a circuit visualization tool

Current Voyeur Development

Currently, we're trying to make Voyeur represent the reasonably disgusting graphs that Carafe generates to represent possible break faults. Here are two images of a two-way and gate and their partial break fault graphs. The blue lines represent normal circuit connections. Red lines and squares are the new breakable connection. Yellow lines represent bridge faults, and green lines represent break faults. This is one of five possible bridge-break combinations possible for this graph. There are 10 bridge faults, 38 break faults, and 11 gate-oxide shorts also possible for this diagram. Displaying them all at once would be chaos, so we've selected only this particular bridge-break connection and it's path.

Layout was generated by VCG for the pretty picture, and drived from a Magic placment for the ugly picture.

The image above is the pretty one (vcg layout)

This is the ugly one (derived from magic placement). Note the overlapping cells.
