Apparatus and method for specifying the configuration of mixed-language simulation models

摘要

An apparatus and method are provided for non-redundantly specifying the configuration of mixed-language models that are intended to be utilized by a simulator to simulate hardware designs. The present invention automatically specifies a configuration of a mixed-language model to be simulated in a simulator. The mixed-language model comprises at least one model written in a source code language and at least one model written in a hardware description language (HDL). First logic identifies hierarchy paths within the source code model. Second logic identifies hierarchy paths within the source code model that correspond to hierarchy paths in the HDL model. Third logic identifies connections within the source code model that are to be enabled or disabled. Fourth logic identifies portions of the source code model that are to be modeled by the source code model and portions of the source code model that are to be modeled by the HDL model. For stand-alone source code model simulations, the present invention comprises first logic that determines whether a stand-alone source code model simulation or a mixed-language simulation is to be performed, and second logic that specifies a first configuration of a library when a stand-alone source code simulation is to be performed, and that specifies a second configuration of the library when a mixed-language simulation is to be performed. Different library configurations enable the library to be used for stand-alone source code model simulation and for mixed-language simulation.
