摘要
从国内实际出发,在分析当前工艺映射技术的基础上,提出从高层次(RTL)和逻辑级两个层次上进行工艺映射的策略.提出并讨论了基于知识的高层次(RTL)工艺映射方法,并将该方法与传统的逻辑级工艺映射方法相结合,建造MLTMMT(Multi-LevelTechnology Mapping for Multi-Target,多层次、多目标工艺映射)系统.在MLTMMT的具体实现上,采用了基于知识与基于算法相结合、知识作为数据与程序分离和知识库动态切换等技术,实现了面向多个工艺目标的工艺映射.最后。
Started from the domestic reality and based on the analysis of the current technology mapping techniques, this paper advances a tactic of making technology mapping from RTL and logic level. It puts forward and discusses the high level technology mapping method based on the knowledge. It combines the method with the traditional technology mapping method in the logic level and establishes the MLTMMT(Multi Level Technology Mapping for Multi Target) system. In the concrete implementation, it adopts such techniques as the method based on the knowledge and algorithms, the knowledge abstracted from the programs and acts as the data, and the dynamic switching of KB(knowledge Base). It realizes the technology mapping for multiple technology targets. At last, it gives some operating examples oriented on 3 kinds of technology mapping in MLTMMT system.
