静态危害发生在组合电路中,可以通过使用冗余门来消除。静电危害分类为:

1. 静电 1 危害:
如果输出当前处于逻辑状态 1,并且在输入更改其状态后,同时输出在稳定为 1 之前变为 0,则它是静态 1 危险。

2. 静电 0 危害:
如果输出当前处于逻辑状态 0 并且在输入更改其状态后,同时输出在稳定为 0 之前变为 1,则它是静态 0 危险。

Static-1 和 Static-0 危害之间的区别:

STATIC-1 HAZARD STATIC-0 HAZARD
Output changes from 1 to 0. Output changes from 0 to 1.
It is false ‘0’ level for a short interval. It is false ‘1’ level for a short interval.
AND-OR circuit produces static-1 hazard. NAND-NOR circuit produces static-0 hazard.
The graph goes from high to low then again high. The graph goes from low to high then again low.
Static-1 hazard with contact networks is a tie set hazard. Static-0 hazard with contact networks is a cut set hazard.
SOP is used for removing static-1 hazard. POS is used for removing static-0 hazard.
We deal with 1s in static-1 hazard. We deal with 0s in static-0 hazard.
