03/19/2022, 5:03 PM@User if it passes on the platform, I' say ignore the local results as long as you are running the exact same project + commit id combination.

@User was it passing locally previously? what changed?
m
Matt Venn
03/19/2022, 5:11 PMyes it was passing locally
Matt Venn
03/19/2022, 5:11 PMthe only thing that changed was reinstalling mpw precheck
Matt Venn
03/19/2022, 5:11 PMso maybe the image got updated?
Matt Venn
03/19/2022, 5:12 PM@User yep, just letting you know that there maybe more of these coming from people using sram
Matt Venn
03/19/2022, 5:12 PMand that if you update the precheck on efabless, then a bunch of projects may start failing

omla
03/19/2022, 5:13 PMwell if they pass the platform, we should be good to go

these are issues that we waived for MPW-4. not sure why local flags them and the platform does not. we may have implemented an exclusion in the drc deck for SRAM and these errors. I need to go back and check.
jeffdi
03/19/2022, 5:39 PM
you are using your own local copy of the SRAM versus the PDK?

03/21/2022, 8:32 AM@User @User I got the same DRC both local and on the platform. @User said they have fixed but we don’t have the latest one.

Matt Venn
03/21/2022, 8:43 AMMine is and i dont have drc
n
Nguyen Dao
03/21/2022, 8:47 AMYou mean the sram macro? the using gds and the one in pdk are the same

03/21/2022, 9:22 AM@User when did you run it on the platform?

m
Marwan Abbas
03/21/2022, 9:26 AM@User And did you check that it's an sram issue?
n
Nguyen Dao
03/21/2022, 9:26 AMI got the same drc errors from local precheck
m
Marwan Abbas
03/21/2022, 9:27 AMWhich precheck version are you using?
n
Nguyen Dao
03/21/2022, 9:27 AMyes, I think so
m
Marwan Abbas
03/21/2022, 9:28 AM@User does precheck use the deck with sram exclusion?
n
Nguyen Dao
03/21/2022, 9:30 AMhow to get the precheck version? I think I’m using the latest one (3-4 days ago)
m
Marwan Abbas
03/21/2022, 9:36 AMI think you're using an old version, starting mpw-5b you shouldn't get that issue
Marwan Abbas
03/21/2022, 9:38 AMBut then again it should work on the platform, so that's a question @User can answer
n
Nguyen Dao
03/21/2022, 9:38 AMthis is from the Makefile
m
Marwan Abbas
03/21/2022, 9:39 AMmpw-5c should work as well
Marwan Abbas
03/21/2022, 9:40 AMgo to the precheck directory and make a
git describe --tagsn
Nguyen Dao
03/21/2022, 9:42 AMOK, I’ll try with mpw-5c
Nguyen Dao
03/21/2022, 9:43 AMbut also, it still fails on the platform?
m
Marwan Abbas
03/21/2022, 9:47 AMI can't comment on that, I'm not familiar with the platform. We'll have to wait for @User to answer that question
m
Matt Venn
03/21/2022, 9:54 AMYeah the fail on the platform is an issue
n
Nguyen Dao
03/21/2022, 12:11 PMUpdate: there is no such DRC with the local mpw-5c precheck.

03/21/2022, 1:09 PM@User I followed the thread and it seems your issue has been resolved, correct ?
n
Nguyen Dao
03/21/2022, 1:20 PMI haven’t run again on the efabless portal but the local precheck with mpw-5c doesn’t show those DRC in the SRAM macro as before.
The other weird DRC is showing as I mentioned in the other chat

03/21/2022, 1:23 PMonce you run on the Efabless platform, report back your results, preferably not in this thread as it has too many conversations to track properly. thanks @User

@User there are new nsd and psd DRC checks in klayout. the SRAM has a few known issues with these rules that are waived with the foundry. the
