The instructions in `mpw-one-b.md`say `git clone <https://github.com/efabless/openlane.git> -b mpw-one-b`but github complains that it doesn't have a branch with that name. I am trying to download openlane again instead of upgrading from rc5 to rc6

it's just a PR. Wait until this is merged to caravel master if you want to use it.

ok, thanks! I was just trying to test that the problems I am seeing were not due to my not having the correct versions

<@U018NEYK53K> it's definetly easier to use as it removes the need for an interactive script if you're still struggling to get a DRC clean user_project_wrapper.

<@U018NEYK53K>: We're reviewing the configs and the process and if it's okay we'll merge it soon. However, it's not a must to follow that path.

<@U01634FSETZ> I generated files for `user_proj_example` that look ok to me but are gigantic, so OpenTriton can't read the stuff in `user_project_wrapper` at all. I never got to the DRC step. So now I just trying to do all the steps in Caravel as distributed to see how that works

<@U018NEYK53K>: Can you share your repo? and I'll take a look when I can (soon).

This is now current (but I wasn't able to merge the latest Caravel, which I am experimenting with separately): <https://github.com/fiberhood/MorphleLogic>

The problem is when doing `make user_project_wrapper` in the openlane directory (OpenTriton takes forever to read the .lef file produced by previous steps) but it is likely that the way to fix this is by changing something in `user_proj_example`

I was trying very hard to have nothing but metal5 and metal4 outside my project in `user_project_wrapper` but now see that in the latest version of Caravel `user_project_wrapper.gds`is full of metal1 horizontal stripes
