Abstract
The area of the circuit to be added for easy testability is reduced. Operations contained in a behavioral description are extracted in an operation analyzing unit; when expanding any operation at the time of behavioral synthesis, if the area of the circuit can be reduced to a greater extent when a DFT is applied to the operation before expansion, a parameter indicating that the operation is not to be expanded at the time of behavioral synthesis is generated and DFT information is added to a DFT library. A behavioral synthesis unit, in accordance with the parameter, generates an RTL description without expanding the operation. A DFT unit implements the DFT by referring to the DFT library, and thereafter expands the operation.
