In this paper, a revised cycle-based algorithm isproposed and implemented in VHDL simulator. Event-driven simulation engine andcycle-based simulation engine have been imbedded in the same simulation environment and can be used to asynchronous design and synchronous design respectively.Thus the simulation performance is improved without losing the flexibility and accuracy of event-driven algorithm.展开更多
文摘Cycle-based algorithm has very high performance for the simulation of synchronous design, but it is confined to synchronous design and it is not asaccurate as event-driven algorithm. In this paper, a revised cycle-based algorithm isproposed and implemented in VHDL simulator. Event-driven simulation engine andcycle-based simulation engine have been imbedded in the same simulation environment and can be used to asynchronous design and synchronous design respectively.Thus the simulation performance is improved without losing the flexibility and accuracy of event-driven algorithm.
