In this chapter, the principles on which mixed-mode circuit-level/logic-level simulation is based have been described. The principal areas of new development concern the interfaces between circuit-level and logic devices, in particular, the mapping of signals across those interfaces and the loads reflected onto analogue nodes by logic devices. The feasibility of mixed-mode simulation has been demonstrated by example and questions of precision and cost of simulation addressed.
