Am having an issue with my submission. When I run `make user_project_wrapper`, it runs just fine, until it gets to Step 30, `Running Magic DRC` , which appears to complete just fine, until it prints `Converting Magic DRC database to various tool-readable formats...` , at which point a process of python3 eats through all 32GB of RAM in my system, followed by a 10GB swapfile, and then crashes the entire OS. What is going on here?

Looks like it finished the DRC step but may have trouble converting the output. Can you find the magic DRC results?

I managed to pass this step by creating a 40GB swapfile. And then it just fails because it found 5 million DRC violations.

I am using the `sky130_sram_2kbyte_1rw1r_32x512_8`  macro in this project, if that matters.

I can disable DRC in the config to allow me to have a look at the generated GDS. Precheck also fails on said GDS, due to DRC errors.

Have you used `GRT_OBS` around sram macro?

For designs with srams, you need to swap the gds sram with the lef version. I thought that was included in the precheck though.

I tried using `GRT_OBS` , and everything was fine after that. Nothing with precheck now.
