MIXED SIGNAL SIMULATION

摘要

A system and method for analog and digital mixed mode simulation. The system and method simulates analog mixed signal (AMS) (300) systems coded in one or a plurality of hardware description languages (HDLs) so that described digital subsystem, analog circuits, and mixed signal interface components. It implements and simulates (AMS) circuits using any standardized and specialized type of application programming interface (API) called a HDL programming language interface (PLIs 305). In it preferred embodiment, the system and method simulates systems coded in the popular verilog-AMS HDL and legacy spice HDLs. Utilization of the PLI allows for a much simplified and improved AMS simulation because the mixed mode engine implemented using the PL1 invokes any commonly available digital simulators for the digital engine(s) and any commonly available analog solvers for the analog engine(s). The system and method combines the accuracy of single kernel AMS simulation with the ease of construction and flexibility data exchange AMS simulation.
