做个四层PCB(four)PCB制作中的冲突个人总结

1

Rule violations count

违反规则的数目

2

Short-Circuit Constraint(Allowed= No)(All),(All)

短线约束=不允许)(全部),(全部)

3

Un-routed net constraint((All))

Un-routed净约束(所有)

PCB线中这些线都没有连上,你把他们都连上就可以了。

4

Clearance constraint(Gap=9mil)(All),(All)

间隙约束(间隙=9mil)(全部),(全部)

5

Power plane connect rule(relief connect)(expansion=20mil)(conductor width=10mil)(air gap = 10mil)(entries=4)(All)

功率平面连接规则(救济连接)(扩展=20mil)(导体宽=10mil)(气隙=10mil)(条目=4)(全部)

6

Width Constraint (Min=8mil) (Max=20mil) (Preferred=15mil) (A1l)

宽度约束(Min = 8 mil)( Max= 20 mil)(优先15mi)(全部)

问题应该出在你没置和实际的冲突,你所设置的最小线宽是25mil,最大线宽也是25mil,默认线宽还是25mil,这本没错,但可能是你的某根GND线不是25mil,或者你用了覆铜,而覆铜的线条(Track Width)也不是25mil,所以才出错!建议在Design的Rule里设置一下Width Constraint的最大和最小线宽,调整到合适范围,就不会报错了。

7

Height Constraint (Min=0mil) (Max=1000mil) (Prefered=500mil) (AlI)

高度约束(Min = 0 mi)( Max = 1000 milD(优先= 500 mil)(全部)

8

Hole Size Constraint (Min=1mil) (Max=100mil) (All)

孔尺寸约束(Min=1mil)(Max=150mil)࿰
