@Mitch Bailey @mehdi, Hi Mitch, I meet an lvs problem, it tells me some part is shorted, Does it belongs to the labels problem of hierarchy? Attached my gds file, original spice, extracted spice, lvs rpt. Thank you!

Your

Y1_BOT

is shorted to

CLK0

and

CLK1B

. If you're using klayout, you can trace the net.

OK, thank you Mitch!
