| 1. | These rules are based on the extraction of all parasitic parameters of the layout and device modeling , including transition behavior , high frequency characteristics of the different materials , and electrostatic couplings to printed circuit board ( pcb ) conductors and to the ground 这些规则是基于抽取pcb的敷线和器件模型的所有寄生参数而建立的,寄生参数的抽取考虑到了瞬态行为,不同材料的高频特性, pcb不同导体和各导体对地间的静电耦合。 |
