Hello All, Thank you for your help and advise in advance! Long story short: I was struggling to get precheck to pass consistency and XOR for a project based on the

caravel_user_project_analog

. The consistency issue was the same SUBMODULE_HOOKS documented above, so I was not concerned about that. But the XOR was funny because I couldn’t open the GDS files outputed. Klayout gives the error message:

Stream has unknown format: ..../user_analog_project_wrapper_erased.gds

After struggling for far longer than I would like to admit, I thought I would see what the GDS output looked like for the example, so I cloned the

caravel_user_project_analog

, installed caravel, and ran the precheck. The precheck repo is installed in the default location. The precheck on the example also failed XOR with the same errors and same odd gds behavior. The message given in the precheck is as follows:

{{STEP UPDATE}} Executing Check 6 of 13: XOR
XOR CHECK FILE NOT FOUND in /Users/micahtseng/Personal/eda/caravel_user_project_analog/precheck_results/02_AUG_2022___23_38_27/logs/xor_check.total
{{XOR CHECK FAILED}} The GDS file has non-conforming geometries.

I am honestly rather stumped at this point and I would appreciate any help and advise! Thank you so much! I have attached the xor_check.log and the precheck.log for the caravel example. As far as I can tell I am using the most up to date versions of all tools, but to verify here are the commit hashes/tags of the repos that I’m using pulled from the git log: `caravel_user_project_analog`:
