Hi everyone, I was trying to run the caravel_user_project provided by efabless, the link to the github is https://github.com/efabless/caravel_user_project_analog/tree/main The documentation to this sample project is given in the link https://github.com/efabless/caravel_user_project_analog/blob/main/docs/source/index.rst while running the precheck they are saying that 'Default', 'GPIO-Defines', 'OEB' checks have failed. Can someone please help me to resolve this issue. Thanking you in advance, Milan

@Milan P Manoj Congratulations on getting the default design through openlane. 1. The precheck is setup up to flag an error if people submit the default design. 2. There is a file

verilog/rtl/user_defines.v

that has the gpio configuration settings. You need to modify this for each gpio according to how you’ll use it. If you don’t plan to use a gpio, you still need to set the configuration for that gpio to a valid value. 3. Not sure why you’re getting an oeb error. That should be clean on the default design.

Thank you Please let me know how to fix the OEB error

Can you find a

cvc.oeb.report

file in your

precheck_results

directory?

Yes sir I'm able to find that file

Can you share it?
