CIRCUIT ANALYSIS

Sneak Circuit Analysis for Locating Wire Segments on Schematic Drawings


The automated sneak circuit analysis is accomplished in three processing phases: (1) the data reduction phase in which the "wire list" generated from the schematic of the circuit is reduced to an ISAM file containing a branch cross-reference table (2) the path derivation phase which uses the data in the branch cross-reference table to examine all possible paths to see which meet the above mentioned two-fold criteria for a possible sneak circuit and (3) the path regeneration phase in which the paths flagged are listed in branch sequence number and then in to-from connector sequence. The output report generated is in a highly usable format that allows the engineer to verify the suspected sneak circuit path by locating the wire segments on the circuit schematic drawings.
