Hi Please check the attached fig.
Now the general Notch rule is some thing like this.
> space between 2 segment of U or O shaped metal/od/poly (notch only) >=0.18
so in the diagram "I" spacing.. that's the part of the Notch rule.
What rules say that when ever there is any notch in the layer then the spacing rule should follow the corresponding rules. This spacing is different from the normal spacing rule that's the reason foundry has a specific rule for this.
Let me know in case if you any further query.
