<!channel> Apologies for the delay on this. The Caravel, Precheck and Caravel User Project repo have all been tagged with

mpw-5

for use with the MPW-5 shuttle.

Thanks for the pointer! I do see some failure on the CI for the

mpw-5

commit on https://github.com/efabless/caravel_user_project/tree/mpw-5 are those non blocking?

@User and the pdk and open pdk commits? The OpenLane commit and VM tags?

yep, I'm also curious about https://github.com/The-OpenROAD-Project/OpenLane

@User is there any update expected for openram and pdk??

@User ^^

Tag mpw-5 for caravel-lite does not have files openlane/user_project_wrapper_empty/fixed_wrapper_cfgs.tcl and openlane/user_project_wrapper_empty/default_wrapper_cfgs.tcl, which are referenced from tag mpw-5 of caravel_user_project file openlane/user_project_wrapper/config.tcl. These files were present in caravel-lite tag mpw-3a. https://github.com/efabless/caravel-lite/tree/main/openlane https://github.com/efabless/caravel_user_project/blob/main/openlane/user_project_wrapper/config.tcl

@User any news on the above issues?

There are

caravel/openlane/user_project_wrapper/fixed_wrapper_cfgs.tcl

and

caravel/openlane/user_project_wrapper/default_wrapper_cfgs.tcl

files. Can you change the

config.tcl

file to reference these?

There are workarounds but I believe that at least fixed_wrapper_cfg.tcl should come from caravel-lite, not from a local copy. Just in case it needs to be changed for everyone. Otherwise one can also delete these files and add properties from them to the local config.tcl.

Sorry for the ambiguity. Totally agree with you. In the above example, caravel = caravel-lite (caravel-lite has been cloned to the caravel directory). It looks like the

caravel(aka caravel-lite)/openlane/user_project_wrapper_empty

, has been deprecated and now all the relevant files are in

caravel/openlane/user_project_wrapper

. These files are from caravel-lite and not a local copy, as per your suggestion. However, as you indicated, the template

caravel_user_project/openlane/user_project_wrapper/config.tcl

does not reflect this. My suggestion was to change this local

config.tcl

to point to the existing files in the caravel-lite repo.

Great, it is nice to know what is the intended usage. Thanks.

maybe we should be overriding OPENLANE tags? the one built into caravel is failing atm
