We present several extensions of the effect?cause analysis method  for fault diagnosis in combinational circuits. First, we extend the analysis to circuits consisting of interconnected modules that are assumed to be internal fault-free. To handle the situation in which the obtained response is incompatible with a fault domain restricted to the I/O pins of modules, we introduce a hierarchical approach that repeats the analysis, every time with a suspected module replaced by its gate model, while the rest of the circuit remains modeled at the module level.
