02/03/2022, 9:35 AM@User @User We are trying to put multiple user macros into the caravel wrapper, and now we have the effect that the vertical power straps in M4 are routed through our macros. This does not happen when we habe only one macro. Do you have an idea what we do wrong?

02/03/2022, 10:13 AMIt's been found on for a while now, but I don't think there is any understanding or solutions yet
Matt Venn
02/03/2022, 10:14 AMI don't even think there is a bug open

Mitch Bailey
02/03/2022, 10:15 AM@User How do you deal with it on your multi-design chips?
m
Matt Venn
02/03/2022, 10:16 AMIt hasn't happened to me yet
Matt Venn
02/03/2022, 10:16 AMI did some investigation here: https://skywater-pdk.slack.com/archives/C017HPHCMEY/p1640343090384300?thread_ts=1640343090.384300&cid=C017HPHCMEY

02/03/2022, 10:17 AMSo I imagine I haven't hit it yet because I'm still using tooling from mpw3

Mitch Bailey
02/03/2022, 10:18 AMlol.

Matt Venn
02/03/2022, 10:19 AMWell I'm still waiting for a new set of tags that work
Matt Venn
02/03/2022, 10:19 AMThe current mpw5 tags don't even install

Mitch Bailey
02/03/2022, 10:23 AMDid you see the workaround I proposed? https://skywater-pdk.slack.com/archives/C01EX4ATEKF/p1643869085558089

Matt Venn
02/03/2022, 10:23 AMYes
Matt Venn
02/03/2022, 10:26 AMI'll try it later and see if I get the pdn issues
Matt Venn
02/03/2022, 2:56 PMok, yes on the main branch of caravel_user_project and editing the makefile I can install openlane, pdk and then build the gds
Matt Venn
02/03/2022, 2:56 PMhave you looked at the precheck? that also seems broken at mpw5 tag.
Matt Venn
02/03/2022, 2:57 PMwants an env var called GOLDEN_CARAVEL
Matt Venn
02/03/2022, 3:14 PMand the docker_mount.sh script is missing setting the CARAVEL_ROOT env var
Matt Venn
02/03/2022, 3:21 PMand the precheck fails to deal with openram, so it fails DRC with 2M errors

02/05/2022, 1:55 AMDo you have an screen shot of the problem? It's not clear to me why the number of macros matters

02/10/2022, 7:50 AM@User I have the same error on
make run-precheckm
Matt Venn
02/10/2022, 7:52 AMI export it manually

Harald Pretl
02/10/2022, 9:04 AMFound and fixed it. Not helping that the error message looks for
GOLDEN_CARAVELCARAVEL_ROOT
