全定制模块视图的产生与IP封装

View-Generation and IP Package for Full-Customized Modules

文章首先说明了将全定制模块用在基于标准单元综合流程中、以及进行硬核IP封装时需要提交的模型与数据。详细分析了模块视图产生的方法、插值算法、Synopsys模型中查找表的跳变时间与负载电容索引点的合理取值、以及全定制模块特征值的类型及提取原理。最后,介绍了“银河飞腾—D4”高性能DSP中的全定制设计模块———桶形移位器与寄存器文件———的视图产生过程。

Models and data needed for full-customized modules used in synthesis design and IP packaging are described. Method for view-generation and algorithm for interpolation are analyzed. And ways to determine proper index values of transition time and pin capacitance used in the lookup table of Synopsys model are also explained, along with the characterization types and its extraction theory. Finally, the view-generating process of a full-customized barrel shifter module and register file module in a high performance DSP is presented.
