02/03/2022, 3:27 PM@User @User what's the status with the openram handling of the precheck? For MPW3 tooling it correctly substituted the lef file and precheck could pass. With MPW5 tagged precheck this doesn't happen and fails with 2M DRC violations.

02/03/2022, 3:45 PMthe precheck on efabless site passes with DRC tho, so I guess it's a different version? It would be helpful to know what that version is
Matt Venn
02/03/2022, 3:46 PMIt fails instead with klayout FEOL, whereas my local precheck gets killed with out of memory before then

02/03/2022, 5:27 PM@User regarding the precheck, the magic check has become more of a warning than a blocking check as Magic has some limitations around ram
and the version of the precheck being used on the efabless site is 'mpw-5' sourced directly from github

02/03/2022, 7:02 PM@User I am getting different results on Efabless precheck and my local checkout. I'm at mpw-5 tag and it's pulling Efabless latest. It doesn't work out of the box I have to set caravel root inside.
Matt Venn
02/03/2022, 7:02 PMAny idea how I can get my local version to match?

02/03/2022, 8:53 PMI am not sure how are you running the precheck, and it shouldn't need you to set anything up. I would suggest following the instructions here to build the docker image again

Matt Venn
02/03/2022, 8:54 PMFollowing the instructions on that page on mpw-5 tag
Matt Venn
02/03/2022, 8:54 PMBut pulling docker image not building

omla
02/03/2022, 8:59 PMcan I ask you to provide me with the
sha256m
Matt Venn
02/03/2022, 9:00 PMCan do tomorrow. Can you tell me how? I'm a docker newbie. I tried to find out what the latest tag really means today and gave up
Matt Venn
02/03/2022, 9:01 PMI much prefer to know the specific tag so I get reproducible resultd

02/04/2022, 4:42 PM@User that looks correct, I am unsure why you are getting different results.
Let's start confirming a few other things
omla
02/04/2022, 4:42 PMlocally how did you build your PDK ?
m
Matt Venn
02/04/2022, 4:43 PMtrying to follow the instructions given recently in the #shuttle channel. mpw-5 tags, then in caravel_user_project run make pdk
Matt Venn
02/04/2022, 4:44 PMis the pdk used for the precheck?
o
omla
02/04/2022, 4:44 PMyes
omla
02/04/2022, 4:44 PMwith a small difference
omla
02/04/2022, 4:45 PMI believe the PDK instructions in the user project don't cover installing SRAM
omla
02/04/2022, 4:45 PMso that might be a clue
