Patent ID: 7672820

Claim:
A computer-readable medium containing instructions executable by at least one processor, the computer-readable medium comprising: one or more instructions for providing an interface for defining a block diagram model representing a system and selecting an input linearization point, an output linearization point, and an operating point, the block diagram model comprising a plurality of blocks; one or more instructions for linearizing the block diagram model based on the input linearization point, the output linearization point, and the operating point to form a linearized model; one or more instructions for analyzing a linearization result of a portion of the block diagram model to determine block level contribution information of the portion toward an overall linearization result of the block diagram model, the portion comprising at least one block but less than the plurality of blocks in the block diagram model; and one or more instructions for outputting information concerning a result of analyzing the linearization result, said information including the block level contribution information.
