Which OpenLane tag currently running?
Workaround edit 
pdn_cfg.tcl
and remove 
-default
switch from the proc
share me the test case which got failed, need to raise Github issue on this
u
I have updated openlane yesterday
Now i have no access to the computer I will share when I can
openroad_issue_reproducible.rar
openroad_issue_reproducible.rar
v
@User I am not facing any issues. which version of openlane currently running?
and openroad app? check your dependencies/*.yml file
u
openroad app: 8d53e9b018dec98fa63e907 I have clonned mpw5c tag yesterday. How can I check the version ?
v
You're using very old one. mpw-6b/6c is there. Just check it #shuttle
u
I was using the latest version and faced with this error. Then @User recommended to use stable versions and got same error again.
v
After updating .yml file have ran 
make
command
u
Yeah just now terminated, same error
a
Try with mpw6 and see if it works. If not then raise an issue on github with reproducibles attached
v
@User after updating .yml file follow below instruction inside OpenLane docker:
update the commit in ./dependencies/tool_metadata.yml then go into docker/ and type 
make build-openroad_app
and after that finishes, 
make merge
try this OpenROAD commit: 
7510fd4dbe19babb99cbf39525c1b4dac1f2be2d
u
After i did what you suggested, still says openroad_app version does not match with the expected one even I have installed the expected one:
Copy code
[ERROR]: The version of openroad_app installed in the environment does not match the one required by the OpenLane flow scripts (installed: 8d53e9b018dec98fa63e907ddeb6c5406f035361, expected: 7510fd4dbe19babb99cbf39525c1b4dac1f2be2d)
changing value on .yml file and running the flow.
Is there any way to continue "make module_name" process ? It takes too much time to take feedback.
v
I have requested @User for openlane version. For time being run with adding following variable in 
config.tcl
set ::env(QUIT_ON_MISMATCHES) 0
u
still same error..
