Hello, all

I have questions on LVS commands and the following are commands.

AS = area(S) * (W / perimeter_inside(S, diff))

AD = area(D) * (W / perimeter_inside(D, diff))

PS = perimeter(S) * W / perimeter_inside(S, diff)

PD = perimeter(D) * W / perimeter_inside(D, diff)

1. Why is it reqired to multiply a factor perimeter_inside(D, diff) when calculationg PD or AD ?

2. What is the physical meaning of perimeter_inside(D, diff) ?

Thanks in advance.

I would like to add one more question.

What is going to happen if perimeter_inside(D, diff) ==0 ?

Thanks
