摘要:

在研究传统交叉开关矩阵结构的基础上,提出一种基于总线结构的扭转型交叉开关矩阵设计.应用线段扭转方法,通过对模块化开关单元的复用和堆叠,可实现交叉开关矩阵的版图.SPICE仿真结果表明,提出的交叉开关矩阵具有均一的延时特性和较低的静态功耗.

Abstract:

A novel twisting-style switch matrix is proposed based on the research into architectures of traditional switch matrixes. By using the method of wire twisting, a single tileable switch cell can be replicated and abutted to form the layout of switch matrix. SPICE simulation demonstrates that the proposed switch matrix presents uniform delay characteristic and lower static power dissipation.

Key words: FPGA, switch matrix, wire twisting, tileable
