1. A test apparatus having a data processing means for processing test data received from a system to be tested, comprising:
- an organization trade-off means for determining the organization of said system in response to interactive requests and in accordance with a specification of said system and for preparing a functional block diagram of said system;
a failure mode and effect analysis list preparation means responsive to said origanization trade-off means for performing a failure mode and effect analysis on said functional block diagram prepared by said organization trade-off means and for preparing a failure mode and effect analysis list in accordance with the results of said failure mode and effect analysis;
a design review means coupled to said organization trade-off means and said failure mode and effect analysis list preparation means, comprisinga learning means for acquiring and learning design knowledge from the results of said organization trade-off means and said failure mode and effect analysis list preparation means,a knowledge base means coupled to said learning means for accumulating the knowledge and design knowledge generated by said learning means, andan inference means coupled to said knowledge base means and said learning means for performing inferences using the knowledge accumulated in said knowledge base means;
a diagnosis rule preparation means responsive to said failure mode and effect analysis list preparation means for preparing a diagnosis rule for determining test data diagnosis from said failure mode and effect analysis list preparation means; and
a diagnosis means responsive to said diagnosis rule preparation means and said data processing means comprising a knowledge data base for registering said diagnosis rule for determining test data diagnosis prepard by said diagnosis rule preparation means and for constructing a data base as an aggregate of diagnosis rules, andan inference function means coupled to said knowledge data base for inferring a result of diagnosis of said test data received from said data processing means by using said aggregate of diagnosis rule in said knowledge data base.
