Abstract :
The authors describe the Mozart-mixed mode (MM) simulation system which was formed by a tight coupling of the Mozart multi-level simulator and the Eldo analog simulator. Mozart-MM spans all the digital levels from behavioral to pseudo-electrical as well as the analog circuit and behavioral levels. This work required the development of a new algorithm to couple a digital simulator with discrete time together with a circuit simulator with adaptable time step. The full Mozart interactivity has been extended to Mozart-MM allowing the user to have direct control of the simulation experiment, including the possibility to conditionally execute commands. New techniques for netlisting, X handling and for the verification of the interface unidirectionally assumption are also presented. The tool has been tested extensively and the results presented demonstrate its performance
