Typical Overflow ?

archive

Hi,

I just wonder how much is the typical horizontal and vertical overflow so that the design be routable. I think this should depend on the number of metal layers in the design, I am using 6 metal layers in my design.

Thanks,

Houman

  • Hi Houman,

    I guess it's hard to pin down a specific number to go by. All of my designs are kind of similar, so I sort of have a "feel" for a set of numbers that works for me. But they may be different for you. Also, as Eng Han mentions, different settings can affect these numbers too. But for 6 metal layers, 1% sounds extremely high. After a few correlations with nanoRoute, you should get a feel for your process.
