Summary :

A hierarchical fault tracing method for VLSIs with bi-directional busses from CAD layout data in the CAD-linked electron beam test system is described. When fault tracing reaches at a cell connected to a bi-directional bus, our method is able to judge the direction of the signal flow, input or output, by using waveforms acquired by an EB tester, in a consistent manner independently of circuit functions as with a previously proposed tracing method for circuits without bi-directional busses.
