Abstract: In a design process of an integrated circuit system, an interface model is generated between a behavioral model described at a behavioral level and an RTL model connected to the behavioral model. The interface model includes protocol converter, bit precision converter and signal converter. The protocol converter converts the protocol of the behavioral model, from which the concept of “clock” is absent, into that of the RTL model to time the behavior represented by the behavioral model with clock pulses for the RTL model. The bit precision converter converts the decimal point representations or bit widths of input/output data. And the signal converter converts signal lines or signal values for an input/output signal of the behavioral model. By providing an interface model like this, the overall system can have its design verified.

Abstract: When a circuit to be designed performs data transmit/receive behavior with other circuits such as a voice codec and a transmitter, not only the circuit to be designed but also the other circuits are provided with test clusters arranged in a hierarchical structure of a specification layer, an behavioral layer, and a function layer as in the VC cluster for the circuit to be designed. The test clusters include data describing the I/O relationship between the circuit to be designed and the other circuits in the specification layer, and data for activating sequence control in the other circuits in the behavioral layer. The VC cluster for the object to be designed includes test clusters for sequence control to be particularized in the function layer. Using the test clusters in the VC cluster, test clusters in the lower-level layer can be generated.
