摘　　要：　提出了一套适用于可编程IP核的布图系统PRPIC(PlacementandRoutingSystemforProgrammableIPCore)。该系统对可编程IP核的结构进行抽象建模,并根据该模型生成用于布图的实际电路的有向资源图,从而可以灵活地支持规模和结构不同的可编程IP核。根据可编程IP核结构和应用等方面的特殊性,对布图算法进行了优化。A placement-and-routing CAD system named PRPIC (Placement and Routing System for Programmable IP Core) is presented, which builds a structural model for different programmable IP core architectures. Based on Directed P & R Resource Graph derived from the structural model, the PRPIC system can handle programmable IP core of different architectures and sizes. The P & R algorithms employed by PRPIC system are also optimized according to the characteristic and application of programmable IP core.
