Abstract:
A computer-implemented method, computerized apparatus and computer program product for modified design debugging using differential trace back. An indication of an interface signal in a time unit in an execution resulting in a value miscompare between a design and a modification thereof is obtained. For each of the design and the modification, a data record detailing each signal value in each time unit, and a structure description detailing all components and interconnections thereamong, are obtained. A suspect root cause of the value miscompare is traced back from the interface signal in the time unit, the tracing back comprising comparing values in the data records of candidate signals selected based on the data records and the structure descriptions.

Claim (Index 9):
A computerized apparatus having a processor and coupled memory, the processor being adapted to perform the steps of:\n obtaining an indication of an interface signal in a time unit in an execution, wherein the execution resulted in a value miscompare between a design and a modification of the design, the value miscompare being observed in the interface signal in the time unit; obtaining a first data record comprising for each time unit of the execution a value in the time unit of each signal of the design; obtaining a second data record comprising for each time unit of the execution a value in the time unit of each signal of the modification of the design; obtaining a first structure description comprising a listing of each component of the design and each interconnection of components of the design, whereby source signals for each signal of the design in each time unit are traceable; obtaining a second structure description comprising a listing of each component of the modification of the design and each interconnection of components of the modification of the design, whereby source signals for each signal of the modification of the design in each time unit are traceable; and, determining a suspect root cause of the value miscompare, the suspect root cause being an antecedent signal of the modification of the design in an antecedent time unit traced back from the interface signal in the time unit, wherein said determining comprises comparing values in the first and second data records other than in the interface signal in the time unit, wherein candidate signals which values thereof being compared are determined based on the first and second data records and the first and second structure descriptions.
