Does anyone knows why the precheck ceases abruptly?

Are there any important changes to my design repo after running chip-level static timing analysis for the project integrated in updated Caravel design(step 2 in mpw7 resubmission). Do I need to keep the reports or anything generated in this step for tape-out?

Hello. In MPW-8, I have passed the online pre-check, but I failed at tape-out step with one DRC violations. How can I fix this?

Hi @Mitch Bailey, I am getting FEOL error on running precheck online . I can see logs in galaxy server. Is there any way to download the feol.xml file ...so that i can verify and correct the error locally??

@Matt Venn @Mitch Bailey , I have resubmitted my repo for MPW7.. Precheck and tapeout succeed. So i have to submit it again or any other step is remaining after tapeout step success??

Hi, the precheck server apparently has stopped running? The precheck status only shows submitted. @Matt Venn can you pls have a check? Thanks

it's taking a while for jobs to start

I'm noticing a delay of at least 5 minutes

your does look stuck though

I'm checking

it has not started over an hour since the job submitted?

it's back running now. thanks

Hi, does anyone know why the XOR failed at the power ring? It seems the power rings are not aligned with the caravel setup? Do I need to change any thing in the user_project_wrappper/config.json for the power rings? Thanks

@jeffdi To me this looks like correct hex literals?

@Matt Venn I took a look at the verilog/rtl/user_defines.v in your RGB repo and it seems to me as if the bit-size of 10 of the constants is too short for the contents, 13 would be better.

Anyone who is facing same type of warning in precheck??

Hi everyone,

I am getting XOR error in my final gds of user project wrapper in precheck at 168 places anyone know how to remove this erreo, like what can be done in building the project that ensures no xor error in prechecks

Hi all I am facing a problem I have uploaded a compressed gds as ".tar.gz" file on github and when cloned to repo folder it wont uncompress as running the file command is showing type of file as ASCII text and also the size of file is 133 bytes instead of 25.8 MB. This is causing the prechecks to fail. What can be done here Thanks and Regards

Is it a requirement to provide source files for a project on the open MPW? This project from MPW8 does not: https://platform.efabless.com/projects/1881 It looks like they just uploaded a GDS file. Edit: Maybe it wasn't selected for the MPW8?

I am having trouble with MPW precheck on the Platform for a private chipignite 2304C project created from .tar.gz. Here is the error:

[03/16/23 16:34:36 PDT] IDENTIFYING PROJECT TYPE FAILED
A single valid GDS was not found. If your project is digital, a GDS file should exist under the project's 'gds' directory named 'user_project_wrapper(.gds/.gds.gz)'.

My uploaded file contains exactly that one file it seems to be looking for:

$ tar ztf 23_03_16_17_16.tar.gz
gds/user_project_wrapper.gds

Is GIT LFS supported by the submission system yet?
