Channel spacing between the Macros

[kumar_eee]

I've 2 macros in my design. One macro has 20 pins & another one has 15 pins.

Now I need to calculate the space required between the macros considering the routing resources.

How do you calculate the space?

Let say Metal routing pitch is .1u and 6 metal layer process.

The formula is (width+spacing x number of pins /vertical routing layers) + spacing. It is better adding an additional spacing because you can avoid violation with the side of macros.
