VHD/sub e/LDO: A new mixed mode simulation

Mixed-mode simulation has recently received increased interest not only in cases where analog and digital circuitries coexist in one integrated circuit, but also for a faster digital and complex circuitry which needs high precision in simulation. The importance of mixed mode simulation is highlighted, and its basic principles are described. VHD/sub e/LDO, a new mixed mode simulation, is presented showing a new feature for the mixed interface and synchronization mechanism. Finally, a practical example showing all these characteristics is presented.<<ETX>>
