Hi, I am getting this error at detailed route. Not sure what the problem is.. Can anyone help?

child killed means in-appropriate exit by flow. It may be any reason. one is memory issue. Just check how much memory utilized and what is your system RAM size

24.1M instances is a large design. I believe OL has some options to increase the docker memory size

follow below format. Set max memory what you have $export DOCKER_MEMORY=16gb $make mount

Thanks for pointing out the reason for the error.. It indeed was a memory issue. We've fixed that. However, I am now getting a new error. Any comments on this?

It means the router doesn't see a good way to access the given pin. Are they offgrid or block in some fashion?

@Aireen Amir Jalal Were you able to solve this issue because we are also getting a similar error.

In general it is helpful to have a screen shot of the area around in the pin in question to get some idea of what the issue might be

@Matt Liberty Do you mean the lef file screenshot?

Matt Liberty

No I mean load the design in a gui (klayout, openroad, magic) and get a screenshot of the pin and it environment

@Matt Liberty Can you please clarify by what you mean by "load the design" because i tried opening the lef file in magic using the command lef read [filename] but i am not able to open it. Is this what you are trying to convey?
m

Matt Liberty

11/09/2021, 5:53 AM
I work on OpenRoad and could advise on that but I don't use magic myself.
I mean the actual layout not just the lef file

Gokul Kuppuswamy

11/09/2021, 5:55 AM
But the actual layout is not yet generated, the flow is getting stopped at detailed routing

Matt Liberty

11/09/2021, 5:56 AM
layout exists before routing happens, save the DEF and open it. I would guess OL does this already after each step

Can you share 24-tritonRoute.log. we will tell DEF file name to load it in klayout

Sorry, I am new to Klayout. Can you kindly explain how to search for it?

No that pin isn't a part of the macro i'm trying to harden

In the issue provided in the link, they have told there is a problem in the lef. But here the lef itself is getting generated by the Openlane flow.

Would you package this error by following below steps and share us https://github.com/The-OpenROAD-Project/OpenLane/blob/master/docs/source/using_or_issue.md and file git hub issue.
this is your def file

Matt Liberty

@Vijayan Krishnan would you zoom to the pin of interest and turn on li1 & met1 layers? The routing tracks are useful as well
