Hello, I am currently using rc4 master branch and I have run my design through it as well. However caravel does not seem to work with rc4. Do I need to switch to

develop

branch of

openlane

to run

caravel

. What's the best combination at the moment? @User @User @User

I'm updating the instructions at the moment. I'll ping you when I have a working setup.

yeah, I'm unable to get make user_proj_example or user_project_wrapper working right now with rc4 or rc5

Yes exactly @Matt Venn. Sure I would be waiting @Amr Gouhar

make user_project_example passes on rc5 after specifying CLOCK_PORT. I also get errors for user_project_wrapper, something due to pdn.tcl or new_pdn.tcl

yeah, what is the difference between clock net and clock port?

Perhaps you also need to switch to rc5 in $caravel/openlane/Makefile. I think those are the only 2 things I did this morning

Also when you run

make user_project_wrapper,

does it run the openlane

interactively

or

non interactively

? I was expecting it to read the file

interactive.tcl

from

openlane/user_project_wrapper

but it did not in my case

@Matt Venn Although it says here that both are required, I suppose only CLOCK_PORT is necessary (or maybe one of the two). I understood CLOCK_PORT as top-level input clock port name, and CLOCK_NET as a hierarchical clock net in the submodule that the designer wishes to specify as clock.

You can try now. Hopefully, it should work..

@Wajeh ul hasan So far, if the interactive.tcl existed, it was ran by default.

@Dejan Petkovic it surely exists, but its being ignored in my case.

@Wajeh ul hasan: try this https://github.com/efabless/caravel/commits/develop
