When I ran efabless' mpw precheck, I got a status of "exception". Checking the log in galaxy did not reveal the details of the exception, so I ran

make run-precheck

on my computer and got the I got the following error:

The log shown in the workspace of efabless is as follows:

[10/25/21 10:52:45 PDT] STEP UPDATE

My project repo is here: https://github.com/cpu-dev/caravel_jacaranda-8 My project is here: https://efabless.com/projects/413 The output of the precheck report does not seem to be working, what could be the cause? Thank you.

Hello Yuki, it seems that the KLayout BEOL fails to write the report, I will be taking a look and letting you know, once I know more

@User how much memory does the computer running precheck on efabless workspace have? If it is less than 16GB, the precheck of my project may crash due to lack of memory (in fact, it did when I tried on my computer).

it does have

16 GBs

of memory, we are trying to identify a fix that get's you over this issue

@User Thank you so much! I'll try it.

@User I’m facing exactly the same issue…

I have 8GB of memory on my Ubuntu VM.

Hello @User, I am not sure why you are hitting this issue, but a good idea is to submit the precheck on the platform and see if the same result shows up, 8GBs of memory might not be enough

@User Hi Ahmed, Thanks a lot for the recommendation. So you mean I should re-run it on the efabless platform, right?

@User yes, the machines being used on the platform has a lot more memory and if you still face a problem there we can offer more helping in figuring out what the issue is.
