@mehdi @Tim Edwards, Hi Tim, can we use this part (red line part) for tapeout? Or just can use the space in the orange line? Thank you very much!

Yes you can. As lone as it passes the prechecks you should be fine.

OK, thank you!

Yes. Look at tech lef. It specifies manufacturing grid 5nm

@Jianwei Jia: I have no idea what the orange line is. There is a boundary line in the "comment" layer (LVS text, I think is the official name) that runs through the middle of the pins right at the boundary. As long as you don't put anything outside that marker line, it will be okay.

OK, I see that, thank you Tim!
