Hello everyone and thanks for contributing to the spread of microelectronics! I'm following the quickstart guide for Caravel user project. After typing the hardening command through OpenLane (make user_proj_example) the following error message is displayed in STEP 37:

[STEP 37]

Could you please provide support?

Which

MPW_TAG

How to check it?

@Mitch Bailey can you please check this?

Right. Just disable for now.

Got it! Thanks for support
