global routing cell - understanding

[bx14zz]

Good Morning friends,


I have a tiny question for you:
Astro use the GRC - global routing cells when he starting the global route.
What is the GRC percentage actually means? If I have a total GRC = 0.1% - what is actually describe? How Astro calculate this number?

Thank you in advance,
faeez
