Does encounter consider the ICG cells as stop point or trace through them during CTs?

Hi.

When doing CTs, how encounter builds clock tree on clock gating clock path.

I mean there are some clock gate (ICG) cells on clock path.

Does encounter consider the ICG cells as stop point or trace through them ?

Thanks!

Hi.
You can select how to do cts and specify ICG cells as stop point or trace through them.

hi

I think it doesn't treat them as stop pin but actually trace thru them to build a clock tree.

Thanks

CTS goes through the AND/OR gate. to reach a leaf pin.
