I'm trying to run a design which instantiates multiple DFFRAM and I'm getting the following:

Check the intermediate DEF to see what's going on.

That seems to be the problem but actually Im not setting the core shape so should I set the

DIE_AREA

or there its a way to keep it automatic ? btw where its located the documentation for the tcl env variables of openlane ?

The automatic size is not very advanced, it doesn't look at the shape of macro or anything, it just tried to pick a square of roughly the right area, irrespective of macro shape or anything.

Thanks for your support, I oversize the design in order to check if it works and now I'm getting a different error and the error.log doesn't show more information than

child process exited abnormally

probably segfault or ran out of memory

I have 16 GB ddr4 ram so Idk what to do to get rid of it.

Instanciating large macros is a pain and oesn't work well ATM. I had to resort to manually specify area, manually placing the macro and using several custom OpenDB scripts to make it work for me. Took me the better part of a week to get a design that places and routes.
