Hello all...!! I did the Routing after CTS in OPENROAD...and it failed due to some error...can anyone pls help me with this...

@Ananya K M I’ve seen this error when macros are placed too close to each other or too close to the sides of the macros. The error message says to open the gds and visually check for congestion. Can you do that?

Shld I look into the area and utilization constraints in config file?? Shld i change its parameters??

Yes, probably

Okay i will try...!!

Are you using hard macros? If so, make sure that they are positioned with enough space between them and enough space to the external pins.

As the message suggests, you should pen the GUI and look at where the congestion is. A screenshot of that would be more informative
