The problem about maxStackLevel

[KYLI0418]

Hi, I'm in the preroute stage now

when i use the "preroute_standard_cells" command

I always receive the same error about maxStackLevel.

I have confirmed that there is no congestion.

Can anyone point me in the direction of modification or inspection?
Thanks!

you do not say which tool you are using or even what you are trying to achieve. really hard to help you without that information
